9\times 2=7x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 9x, the least common multiple of x,9.
18=7x
Multiply 9 and 2 to get 18.
7x=18
Swap sides so that all variable terms are on the left hand side.
x=\frac{18}{7}
Divide both sides by 7.
