6x-8x-\left(-10\right)=87-\left(21+10x\right)
To find the opposite of 8x-10, find the opposite of each term.
6x-8x+10=87-\left(21+10x\right)
The opposite of -10 is 10.
-2x+10=87-\left(21+10x\right)
Combine 6x and -8x to get -2x.
-2x+10=87-21-10x
To find the opposite of 21+10x, find the opposite of each term.
-2x+10=66-10x
Subtract 21 from 87 to get 66.
-2x+10+10x=66
Add 10x to both sides.
8x+10=66
Combine -2x and 10x to get 8x.
8x=66-10
Subtract 10 from both sides.
8x=56
Subtract 10 from 66 to get 56.
x=\frac{56}{8}
Divide both sides by 8.
x=7
Divide 56 by 8 to get 7.
