650\times 12=x\times 2
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 650x, the least common multiple of x,650.
7800=x\times 2
Multiply 650 and 12 to get 7800.
x\times 2=7800
Swap sides so that all variable terms are on the left hand side.
x=\frac{7800}{2}
Divide both sides by 2.
x=3900
Divide 7800 by 2 to get 3900.
