Linear Equations in One Variable

An algebraic expression is the combination of variables and constants. An equation of the form ax + b = c, where a, b, c are real numbers with non-zero value of ‘a’ is called linear equation in one variable. The highest power of the variable in linear equation is one. An equation is a conditi ....Read More

Linear Inequalities

A linear inequation in the variable x can be written in any one of the following forms: (i) ax + b < 0 (ii) ax + b > 0 (iii) ax + b ≤ 0 (iv) ax + b ≥ 0 where a and b are real numbers, a ≠ 0. To solve an inequality, we must have a set of values out of which some may b ....Read More
