You would do the opposite of subtracting which is adding to -10 so add 10 to -10 and add 10 to -20. The -10 now equals 0 so we can get rid of that. Now we have 5x=-10. To get rid of the 5, do the opposite of multiplying and divide 5 from 5x and divide 5 from -10. We now have x=-2! This is your final answer!

5x-10= -20
- add 10 to both sides (
5x= -10)
- divide each side by 5 (
x= -2)
so, the answer is
x= -2)))

to check is answer correct plug it in your equation!
5(-2)-10 = -20
-20 = -20
