To determine To solve: The equation 15 − 2 x = x . Explanation The given equation is 15 − 2 x = x . Square both sides as follows. ( 15 − 2 x ) 2 = ( x ) 2 ( 15 − 2 x ) = x 2 15 − 2 x − x 2 = 0 ( x − 3 ) ( x + 5 ) = 0 On further simplification, ( x − 3 ) = 0 or ( x + 5 ) = 0 x = 3 or x = − 5 Therefore, the solution of equation is x = 3 or x = − 5 . Check the solution by substituting x = 3 in 15 − 2 x = x

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
