18=9\left(x+10\right)
Variable x cannot be equal to -10 since division by zero is not defined. Multiply both sides of the equation by x+10.
18=9x+90
Use the distributive property to multiply 9 by x+10.
9x+90=18
Swap sides so that all variable terms are on the left hand side.
9x=18-90
Subtract 90 from both sides.
9x=-72
Subtract 90 from 18 to get -72.
x=\frac{-72}{9}
Divide both sides by 9.
x=-8
Divide -72 by 9 to get -8.
