Solve for x.

6 - 2x - x = 18

A.

-24

B.

-12

C.

-8

D.

-4

6 - 2x - x = 18

Simplify both sides of the equation.

6 - 2x - x = 18

6 + - 2x + - x = 18

( - 2x + - x) + (6) = 18

- 3x + 6 = 18

- 3x + 6 = 18

Subtract 6 from both sides.

- 3x + 6 - 6 = 18-6

- 3x = 12

Divide both sides by - 3.

- 3x / - 3 = 12 / - 3

x = - 4

Answer:

x = - 4
