9\times 9=3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
81=3x
Multiply 9 and 9 to get 81.
3x=81
Swap sides so that all variable terms are on the left hand side.
x=\frac{81}{3}
Divide both sides by 3.
x=27
Divide 81 by 3 to get 27.
