72\left(6+x\right)=x\times 120
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 72x, the least common multiple of x,72.
432+72x=x\times 120
Use the distributive property to multiply 72 by 6+x.
432+72x-x\times 120=0
Subtract x\times 120 from both sides.
432-48x=0
Combine 72x and -x\times 120 to get -48x.
-48x=-432
Subtract 432 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-432}{-48}
Divide both sides by -48.
x=9
Divide -432 by -48 to get 9.
