8x-3x-2=2x+16
To find the opposite of 3x+2, find the opposite of each term.
5x-2=2x+16
Combine 8x and -3x to get 5x.
5x-2-2x=16
Subtract 2x from both sides.
3x-2=16
Combine 5x and -2x to get 3x.
3x=16+2
Add 2 to both sides.
3x=18
Add 16 and 2 to get 18.
x=\frac{18}{3}
Divide both sides by 3.
x=6
Divide 18 by 3 to get 6.
