Question

What x value makes this equation true -12x - 2(x+9) = 5(x+4)

A. -2
B. 13/19
C. 5
D. -1/3

Answer 1

A

Explanation:

Given

- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides )

- 12x - 2x - 18 = 5x + 20 , that is

- 14x - 18 = 5x + 20 ( subtract 5x from both sides )

- 19x - 18 = 20 ( add 18 to both sides )

- 19x = 38 ( divide both sides by - 19 )

x = - 2 → A
