Question

help with 13+7=32-x and show your work

Answer 1

Alrighty, so the first thing you can do is simplify a little bit :)
Just add the 13 and 7 together...

20 = 32 - x

Now we isolate 'x'

20 = 32 - x
-32 - 32

Now your equation should look like this:

-12 = -x

Now are last step is to divide both sides of the equation by -1 :)

-12 = -x
/-1 /-1

12 = x

and ta da! x is equal to 12! :)
