Solve for x if 2 (5x + 2) 2 = 48

x = 2

step 1:

(2 • (5x + 2) • 2) - 48 = 0

step 2:

4 • (5x + 2) - 48 = 0

Pulling out like terms:

20x - 40 = 20 • (x - 2)

step 4:

20 • (x - 2) = 0

Equations which are never true:

Solve : 20 = 0

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

Solve : x-2 = 0

Add 2 to both sides of the equation:

x = 2
