x\times 80000=\left(x+400\right)\times 64000
Variable x cannot be equal to any of the values -400,0 since division by zero is not defined. Multiply both sides of the equation by x\left(x+400\right), the least common multiple of x+400,x.
x\times 80000=64000x+25600000
Use the distributive property to multiply x+400 by 64000.
x\times 80000-64000x=25600000
Subtract 64000x from both sides.
16000x=25600000
Combine x\times 80000 and -64000x to get 16000x.
x=\frac{25600000}{16000}
Divide both sides by 16000.
x=1600
Divide 25600000 by 16000 to get 1600.
