Question

Solve for x: 3x − 2(6 − x) = 7x + 2(5 + x) − 6 A) −4 B) −2 C) 2 D) 4

Answer 1

x = - 4

Explanation:

Given

3x - 2(6 - x) = 7x + 2(5 + x) - 6 ← distribute parenthesis on both sides

3x - 12 + 2x = 7x + 10 + 2x - 6, that is

5x - 12 = 9x + 4 ( subtract 9x from both sides )

- 4x - 12 = 4 ( add 12 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4 → A
