Solve 16 = 8 + x.

A. x = 2

B. x = 24

C. x = 8

D. x = 128

Pulling out like terms:

3.1 Pull out like factors:

24 - 8x = - 8 • (x - 3)

Equation at the end of step 3 : - 8 • (x - 3) = 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-3 = 0

Add 3 to both sides of the equation:

x = 3

One solution was found : x = 2

Well it’s obviously C (8) because 8+8=16
