Question

Find the exact solution to the equation.
4(12-3x) = 64

What is the solution?

Answer 1

x = -4/3

Explanation:

4(12 - 3x) = 64

open the parenthesis

4 * 12 - 4 * 3x = 64

48 - 12x = 64

subtract 48 from both sides

48 - 48 - 12x = 64 - 48

-12x = 64 - 48

-12x = 16

divide both sides by -12

12x/-12 = 16/-12

x = 16/-12

x = -4/3
