Solve the equation. - x + 8 + 3x = x - 6

-x+8+3x=x-6

8+2x=x-6

+6 + 6

14+2x=x

-2x - 2x

14/-1=-x/-1

-14=x

First group the coefficients together on their side of the equal sign.

-x + 3x = 2x.

Then, since it is a positive number, subtract it from that side and the other side.

On the other side, the x becomes - x.

Add the 6 from the other side to the 8 to make 14.

14 = - x

Divide both sides by - 1, to get the answer.

x = - 14
