8x-2x-1=3x-10
To find the opposite of 2x+1, find the opposite of each term.
6x-1=3x-10
Combine 8x and -2x to get 6x.
6x-1-3x=-10
Subtract 3x from both sides.
3x-1=-10
Combine 6x and -3x to get 3x.
3x=-10+1
Add 1 to both sides.
3x=-9
Add -10 and 1 to get -9.
x=\frac{-9}{3}
Divide both sides by 3.
x=-3
Divide -9 by 3 to get -3.
