Question

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

Answer 1

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.
