Answer:
Simplifying
4(x + 5) = 32
Reorder the terms:
4(5 + x) = 32
(5 * 4 + x * 4) = 32
(20 + 4x) = 32
Solving
20 + 4x = 32
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 4x = 32 + -20
Combine like terms: 20 + -20 = 0
0 + 4x = 32 + -20
4x = 32 + -20
Combine like terms: 32 + -20 = 12
4x = 12
Divide each side by '4'.
x = 3
Simplifying
x = 3
