1000\times 3=x\times 30
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 1000x, the least common multiple of x,1000.
3000=x\times 30
Multiply 1000 and 3 to get 3000.
x\times 30=3000
Swap sides so that all variable terms are on the left hand side.
x=\frac{3000}{30}
Divide both sides by 30.
x=100
Divide 3000 by 30 to get 100.
