\left(x+20\right)\times 4000=x\times 6000
Variable x cannot be equal to any of the values -20,0 since division by zero is not defined. Multiply both sides of the equation by x\left(x+20\right), the least common multiple of x,x+20.
4000x+80000=x\times 6000
Use the distributive property to multiply x+20 by 4000.
4000x+80000-x\times 6000=0
Subtract x\times 6000 from both sides.
-2000x+80000=0
Combine 4000x and -x\times 6000 to get -2000x.
-2000x=-80000
Subtract 80000 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-80000}{-2000}
Divide both sides by -2000.
x=40
Divide -80000 by -2000 to get 40.
