\left(x-500\right)\times 90000=x\times 80000
Variable x cannot be equal to any of the values 0,500 since division by zero is not defined. Multiply both sides of the equation by x\left(x-500\right), the least common multiple of x,x-500.
90000x-45000000=x\times 80000
Use the distributive property to multiply x-500 by 90000.
90000x-45000000-x\times 80000=0
Subtract x\times 80000 from both sides.
10000x-45000000=0
Combine 90000x and -x\times 80000 to get 10000x.
10000x=45000000
Add 45000000 to both sides. Anything plus zero gives itself.
x=\frac{45000000}{10000}
Divide both sides by 10000.
x=4500
Divide 45000000 by 10000 to get 4500.
