\frac{4+5}{x}=6\times 3
Multiply both sides by 3.
4+5=6\times 3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
9=6\times 3x
Add 4 and 5 to get 9.
9=18x
Multiply 6 and 3 to get 18.
18x=9
Swap sides so that all variable terms are on the left hand side.
x=\frac{9}{18}
Divide both sides by 18.
x=\frac{1}{2}
Reduce the fraction \frac{9}{18} to lowest terms by extracting and canceling out 9.
