Pulling out like terms

3.1     Pull out like factors :

  8x - 48  =   8 • (x - 6)

Equation at the end of step

3

:

 8 • (x - 6)  = 0

STEP

4

:

Equations which are never true:

4.1      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2      Solve  :    x-6 = 0

Add  6  to both sides of the equation :

                     x = 6

One solution was found :

x = 6
