8x=\left(x+20\right)\times 16
Variable x cannot be equal to -20 since division by zero is not defined. Multiply both sides of the equation by 8\left(x+20\right), the least common multiple of 20+x,8.
8x=16x+320
Use the distributive property to multiply x+20 by 16.
8x-16x=320
Subtract 16x from both sides.
-8x=320
Combine 8x and -16x to get -8x.
x=\frac{320}{-8}
Divide both sides by -8.
x=-40
Divide 320 by -8 to get -40.
