\left(x+20\right)\times 2000=2x\times 1400
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.
2000x+40000=2x\times 1400
Use the distributive property to multiply x+20 by 2000.
2000x+40000=2800x
Multiply 2 and 1400 to get 2800.
2000x+40000-2800x=0
Subtract 2800x from both sides.
-800x+40000=0
Combine 2000x and -2800x to get -800x.
-800x=-40000
Subtract 40000 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-40000}{-800}
Divide both sides by -800.
x=50
Divide -40000 by -800 to get 50.
