How to solve - 8-x=x-4x

Okay. So for this question, let's combine like terms on the right side first to simplify the expression. x - 4x is - 3x. The expression simplified is this:

-8 - x = - 3x.

Now, we add x to both sides to cancel out the x on the left. - 3x + x is - 2x. That leaves us with - 8 = - 2x. Divide each side by - 2 to isolate the x. - 2x/-2 cancels out. - 8/-2 is 4. Let's plug in the value as x to see if it works. - 8 - 4 is - 12. - 3 * 4 is - 12. - 12 = - 12. There. x = 4.
