The linear equation is an algebraic equation which gives a straight line. Where each term is either a product of a constant or a constant and a single variable. It is equal to the product that is directly proportional to the other plus the constant. The origin of the name "linear" comes from the fact that the set of solutions of an equation forms a straight line in the plane.

The

Where,

Since terms of linear equations cannot contain products of distinct or equal variables, nor any power (other than 1) or other function of a variable, equations involving terms such as xy, x2, y1/3, and sin(x) are nonlinear.

Given function is 5x + 6 = 11

5x = 11 - 6

x = $\frac{5}{5}$ = 1

$\therefore$ x = 1.

Given function is 7x + (-9) = 12

7x = 12 + 9

x = $\frac{21}{7}$ = 3

$\therefore$ x = 3
