-32-72x=7\left(-2-11x\right)
Use the distributive property to multiply -8 by 4+9x.
-32-72x=-14-77x
Use the distributive property to multiply 7 by -2-11x.
-32-72x+77x=-14
Add 77x to both sides.
-32+5x=-14
Combine -72x and 77x to get 5x.
5x=-14+32
Add 32 to both sides.
5x=18
Add -14 and 32 to get 18.
x=\frac{18}{5}
Divide both sides by 5.
