-3x-9=-6x+8-4x+3
Combine 2x and -5x to get -3x.
-3x-9=-10x+8+3
Combine -6x and -4x to get -10x.
-3x-9=-10x+11
Add 8 and 3 to get 11.
-3x-9+10x=11
Add 10x to both sides.
7x-9=11
Combine -3x and 10x to get 7x.
7x=11+9
Add 9 to both sides.
7x=20
Add 11 and 9 to get 20.
x=\frac{20}{7}
Divide both sides by 7.
