x\times 30=210\times 7
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 210x, the least common multiple of 210,x.
x\times 30=1470
Multiply 210 and 7 to get 1470.
x=\frac{1470}{30}
Divide both sides by 30.
x=49
Divide 1470 by 30 to get 49.
