Question

I need this answer like now nfgl. Select the correct answer. Which value of x makes this equation true? -12x - 2(x + 9) = 5(x + 4) A. 13/19 B. 5 C. -1/3 D. -2

Answer 1

D

Explanation:

1. Simplify each side of the given equation:

-12x -2(x+9) = 5(x+4) ==> -12x -2x -18 = 5x +20

==> -14x -18 = 5x+20

2. Subtract 5x from both sides and add 18 to both sides:

-14x -5x = 20 +18 ==> -19x = 38

3. Divide both sides by -19: x = 38 / -19 = -2

Answer 2

D

Explanation:

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

- 12x - 2x - 18 = 5x + 20

- 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
