Hello there!

-5 = -8 -x
First, we need to get x isolated (put on one side of the equation by itself), and then divide by -1 to get rid of the negative sign.
Add 8 to both sides.
-5 + 8 = 3
-8 + 8 = 0
You are left with:
-x = 3
Now, we must divide both sides by -1 to solve for x.
-x / -1 = x
3 / -1 = -3
You are now left with the following solution:
x = -3

I hope this helps!
