x+2=-9\left(x-8\right)
Variable x cannot be equal to 8 since division by zero is not defined. Multiply both sides of the equation by x-8.
x+2=-9x+72
Use the distributive property to multiply -9 by x-8.
x+2+9x=72
Add 9x to both sides.
10x+2=72
Combine x and 9x to get 10x.
10x=72-2
Subtract 2 from both sides.
10x=70
Subtract 2 from 72 to get 70.
x=\frac{70}{10}
Divide both sides by 10.
x=7
Divide 70 by 10 to get 7.
