\left(x+1\right)\times 30=x\times 20
Variable x cannot be equal to any of the values -1,0 since division by zero is not defined. Multiply both sides of the equation by x\left(x+1\right), the least common multiple of x,x+1.
30x+30=x\times 20
Use the distributive property to multiply x+1 by 30.
30x+30-x\times 20=0
Subtract x\times 20 from both sides.
10x+30=0
Combine 30x and -x\times 20 to get 10x.
10x=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-30}{10}
Divide both sides by 10.
x=-3
Divide -30 by 10 to get -3.
