36-8-\left(-x\right)=x+2-\left(5-x\right)
To find the opposite of 8-x, find the opposite of each term.
36-8+x=x+2-\left(5-x\right)
The opposite of -x is x.
28+x=x+2-\left(5-x\right)
Subtract 8 from 36 to get 28.
28+x=x+2-5-\left(-x\right)
To find the opposite of 5-x, find the opposite of each term.
28+x=x+2-5+x
The opposite of -x is x.
28+x=x-3+x
Subtract 5 from 2 to get -3.
28+x=2x-3
Combine x and x to get 2x.
28+x-2x=-3
Subtract 2x from both sides.
28-x=-3
Combine x and -2x to get -x.
-x=-3-28
Subtract 28 from both sides.
-x=-31
Subtract 28 from -3 to get -31.
x=31
Multiply both sides by -1.
