9-\left(x-2x-3+7\right)-1=10
To find the opposite of 2x+3, find the opposite of each term.
9-\left(-x-3+7\right)-1=10
Combine x and -2x to get -x.
9-\left(-x+4\right)-1=10
Add -3 and 7 to get 4.
9-\left(-x\right)-4-1=10
To find the opposite of -x+4, find the opposite of each term.
9+x-4-1=10
The opposite of -x is x.
5+x-1=10
Subtract 4 from 9 to get 5.
4+x=10
Subtract 1 from 5 to get 4.
x=10-4
Subtract 4 from both sides.
x=6
Subtract 4 from 10 to get 6.
