Q.1
$\begin{array}{l}\mathrm{Solve}\mathrm{the}\mathrm{following}\mathrm{equations}:\\ \left(\mathrm{a}\right)2\mathrm{y}+\frac{5}{2}=\frac{37}{2}\left(\mathrm{b}\right)5\mathrm{t}+28=10\left(\mathrm{c}\right)\frac{\mathrm{a}}{5}+3=2\\ \left(\mathrm{d}\right)\frac{\mathrm{q}}{4}+7=5\left(\mathrm{e}\right)\frac{5}{2}\mathrm{x}=10\left(\mathrm{f}\right)\frac{5}{2}\mathrm{x}=\frac{25}{4}\\ \left(\mathrm{g}\right)7\mathrm{m}+\frac{19}{2}=13\left(\mathrm{h}\right)6\mathrm{z}+10=2\left(\mathrm{i}\right)\frac{3\mathrm{l}}{2}=\frac{2}{3}\\ \left(\mathrm{j}\right)\frac{2\mathrm{b}}{3}5=3\end{array}$
Ans.
\begin{array}{l}\left(\text{a}\right)\text{2}y+\frac{5}{2}=\frac{37}{2}\\ 2y=\frac{37}{2}\frac{5}{2}=\frac{375}{2}=\frac{32}{2}=16\\ 2y=16\\ y=\frac{16}{2}=8\\ Thus,\text{\hspace{0.17em}}\overline{)y=8}\\ \left(\text{b}\right)\text{5t}+\text{28}=\text{1}0\\ 5t=1028\\ 5t=18\\ \overline{)t=\frac{18}{5}}\\ \left(\text{c}\right)\frac{\text{a}}{5}+3=2\\ \frac{a}{5}=23\\ \frac{a}{5}=1\\ \overline{)a=5}\\ \left(\text{d}\right)\frac{q}{4}+7=5\\ \frac{q}{4}=57\\ \frac{q}{4}=2\\ \overline{)q=8}\\ \left(\text{e}\right)\frac{5}{2}x=10\\ 5x=10\times 2\\ x=\frac{10\times 2}{5}=\frac{\overline{)5}\times 2\times 2}{\overline{)5}}=4\\ Thus,\text{\hspace{0.17em}}\overline{)x=4}\\ \left(\text{f}\right)\frac{5}{2}x=\frac{25}{4}\\ 5x=\frac{25\times 2}{4}\\ x=\frac{\overline{)5}\times 5\times \overline{)2}}{\overline{)2}\times 2\times \overline{)5}}\\ Thus,\text{\hspace{0.17em}}\overline{)x=\frac{5}{2}}\\ \left(\text{g}\right)7m+\frac{19}{2}=13\\ 7m=13\frac{19}{2}=\frac{2619}{2}=\frac{7}{2}\\ 7m=\frac{7}{2}\\ m=\frac{\overline{)7}}{2\times \overline{)7}}\\ Thus,\text{\hspace{0.17em}}\overline{)m=\frac{1}{2}}\\ \left(\text{h}\right)\text{6z}+\text{1}0=\text{2}\\ 6z=210\\ 6z=12\\ z=\frac{12}{6}=\frac{2\times \overline{)6}}{\overline{)6}}0\\ Thus,\text{\hspace{0.17em}}\overline{)z=2}\\ \left(\text{i}\right)\frac{3l}{2}=\frac{2}{3}\\ 3l=\frac{4}{3}\\ \overline{)l=\frac{4}{9}}\\ \left(\text{j}\right)\frac{2b}{3}5=3\\ \frac{2b}{3}=8\\ 2b=24\\ b=\frac{24}{2}=\frac{\overline{)2}\times 12}{\overline{)2}}\\ Thus,\text{\hspace{0.17em}}\overline{)b=12}\end{array}
Q.2
$\begin{array}{l}\mathrm{Solve}\mathrm{the}\mathrm{following}\mathrm{equations}:\\ \left(\mathrm{a}\right)2(\mathrm{x}+4)=12\left(\mathrm{b}\right)3(\mathrm{n}5)=21\left(\mathrm{c}\right)3(\mathrm{n}5)=21\\ \left(\mathrm{d}\right)32(2\mathrm{y})=7\left(\mathrm{e}\right)4(2\mathrm{x})=9\left(\mathrm{f}\right)4(2\mathrm{x})=9\\ \left(\mathrm{g}\right)4+5(\mathrm{p}1)=34\left(\mathrm{h}\right)345(\mathrm{p}1)=4\end{array}$
Ans.
\begin{array}{l}\text{(a})\text{}2(x+\text{}4)=12\\ \text{Divide both sides by 2 to get}\\ x+4=6\\ \text{Thus,}\text{\hspace{0.17em}}\overline{)x=2}\\ \left(\text{b}\right)\text{}3(n5)=21\\ \text{Divide both sides by 3 to get}\\ n5=\text{7}\\ \text{Thus,}\overline{)\text{}n=2}\\ \left(\text{c}\right)\text{}3(n5)=\text{21}\\ \text{Divide both sides by 2 to get}\\ n5=7\\ Thus,\text{\hspace{0.17em}}\overline{)n=12}\\ \left(\text{d}\right)\text{3}\text{2}(\text{2}y)=\text{7}\\ 2\left(2y\right)=4\\ \text{Divide both sides by}\text{2 to get}\\ 2y=2\\ \text{Multiply both sides by}\text{1 to get}\\ y2=2\\ \text{Thus,}\overline{)y=4}\\ \left(\text{e}\right)\text{}4(2x)=\text{9}\\ \text{Divide both sides by}\text{4 to get}\\ \text{2}x=\frac{9}{4}\\ \text{Multiply both sides by}\text{1 to get}\\ x2=\frac{9}{4}\\ x=\frac{9}{4}+2=\frac{9+8}{4}\\ Thus,\text{\hspace{0.17em}}\overline{)x=\frac{17}{4}}\\ \left(\text{f}\right)\text{}4(2x)=\text{9}\\ \text{Divide both sides by 4 to get}\\ \text{2}x=\frac{9}{4}\\ \text{Multiply both sides by 1 to get}\\ \text{x}2=\frac{9}{4}\\ x=\frac{9}{4}+2=\frac{9+8}{4}\\ \text{Thus},\text{\hspace{0.17em}}\overline{)x=\frac{1}{4}}\\ \left(\text{g}\right)\text{}4+5\text{}(p1)=34\\ 5\left(p1\right)=30\\ \text{Divide both sides by 5 to get}\\ \text{p}1=6\\ p=6+1=7\\ \text{Thus},\text{\hspace{0.17em}}\overline{)p=7}\\ \left(\text{h}\right)\text{}345(p1)=4\\ 5\left(p1\right)=30\\ \text{Divide both sides by}\text{5 to get}\\ p1=6\\ p=6+1=7\\ \text{Thus,}\text{\hspace{0.17em}}\overline{)p=7}\end{array}
Q.3
$\begin{array}{l}\mathrm{Solve}\mathrm{the}\mathrm{following}\mathrm{equations}.\\ \left(\mathrm{a}\right)4=5(\mathrm{p}2)\left(\mathrm{b}\right)4=5(\mathrm{p}2)\left(\mathrm{c}\right)16=5(2\mathrm{p})\\ \left(\mathrm{d}\right)10=4+3(\mathrm{t}+2)\left(\mathrm{e}\right)28=4+3(\mathrm{t}+5)\\ \left(\mathrm{f}\right)0=16+4(\mathrm{m}6)\end{array}$
Ans.
\begin{array}{l}\left(\text{a}\right)\text{4}=\text{5}(p\text{2})\\ \text{Divide both sides by 5 to get}\\ \frac{4}{5}=p2\\ p=\frac{4}{5}+2=\frac{4+10}{5}\\ \text{Thus},\text{\hspace{0.17em}}\overline{)p=\frac{14}{5}}\\ \left(\text{b}\right)\text{4}=\text{5}(p2)\\ \text{Divide both sides by 5 to get}\\ \frac{4}{5}=p2\\ p=\frac{4}{5}+2=\frac{4+10}{5}\\ \text{Thus},\text{\hspace{0.17em}}\overline{)p=\frac{6}{5}}\\ \left(\text{c}\right)16=5\text{}(2p)\\ \text{Divide both sides by}\text{5 to get}\\ \frac{16}{5}=2p\\ \text{Multiply both sides by}\text{1 to get}\\ \frac{\text{16}}{5}=p2\\ p=\frac{16}{5}+2=\frac{16+10}{5}\\ \text{Thus},\text{\hspace{0.17em}}\overline{)p=\frac{6}{5}}\\ \left(\text{d}\right)\text{1}0=\text{4}+\text{3}(t+2)\\ 6=3\left(t+2\right)\\ \text{Divide both sides by 3 to get}\\ 2=t+2\\ \text{Thus,}\overline{)t=0}\\ \left(\text{e}\right)\text{28}=\text{4}+\text{3}(t+\text{5})\\ 24=3\left(t+5\right)\\ \text{Divide both sides by 3 to get}\\ 8=t+5\\ \text{Thus,}\overline{)t=3}\\ \left(\text{f}\right)0=\text{16}+\text{4}(m\text{6})\\ 16=4\left(m6\right)\\ \text{Divide both sides by 4 to get}\\ 4=m6\\ \text{Thus,}\overline{)m=2}\end{array}
Q.4
$\begin{array}{l}\left(\mathrm{a}\right)\mathrm{Construct}3\mathrm{equations}\mathrm{starting}\mathrm{with}\mathrm{x}=2\\ \left(\mathrm{b}\right)\mathrm{Construct}3\mathrm{equations}\mathrm{starting}\mathrm{with}\mathrm{x}=2\end{array}$
Ans.
\begin{array}{l}\text{(a) We have}\\ x=2\\ \text{Multiply both sides by 4 to get}\\ \overline{)4x=8}\dots \dots \dots \dots \left(\text{i}\right)\\ \text{Subtract 2 from both sides to get}\\ \overline{)4x2=6}\dots \dots \left(\text{ii}\right)\\ \text{Divide both sides by 2 to get}\\ \overline{)2x1=3}\dots \dots \text{(iii)}\\ \text{(b)}\text{\hspace{0.17em}}\text{We have}\\ x=2\\ \text{Adding 4 to both sides to get}\\ \overline{)x+4=2}\dots \dots \dots \left(\text{i}\right)\\ \text{Multiply 2 from both sides to get}\\ \overline{)2x+8=4}\dots \dots \left(\text{ii}\right)\\ \text{Divide both sides by 2 to get}\\ \overline{)x+4=2}\dots \dots \left(\text{iii}\right)\end{array}
