5+11x-4x-8-3x=10x+9
Use the distributive property to multiply -2 by 2x+4.
5+7x-8-3x=10x+9
Combine 11x and -4x to get 7x.
-3+7x-3x=10x+9
Subtract 8 from 5 to get -3.
-3+4x=10x+9
Combine 7x and -3x to get 4x.
-3+4x-10x=9
Subtract 10x from both sides.
-3-6x=9
Combine 4x and -10x to get -6x.
-6x=9+3
Add 3 to both sides.
-6x=12
Add 9 and 3 to get 12.
x=\frac{12}{-6}
Divide both sides by -6.
x=-2
Divide 12 by -6 to get -2.
