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
