485\times 4000=x\times 8000
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 485x, the least common multiple of x,485.
1940000=x\times 8000
Multiply 485 and 4000 to get 1940000.
x\times 8000=1940000
Swap sides so that all variable terms are on the left hand side.
x=\frac{1940000}{8000}
Divide both sides by 8000.
x=\frac{485}{2}
Reduce the fraction \frac{1940000}{8000} to lowest terms by extracting and canceling out 4000.
