7x-2x-8=9x-16
To find the opposite of 2x+8, find the opposite of each term.
5x-8=9x-16
Combine 7x and -2x to get 5x.
5x-8-9x=-16
Subtract 9x from both sides.
-4x-8=-16
Combine 5x and -9x to get -4x.
-4x=-16+8
Add 8 to both sides.
-4x=-8
Add -16 and 8 to get -8.
x=\frac{-8}{-4}
Divide both sides by -4.
x=2
Divide -8 by -4 to get 2.
