x\times \frac{9}{4.5}=7
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times \frac{90}{45}=7
Expand \frac{9}{4.5} by multiplying both numerator and the denominator by 10.
x\times 2=7
Divide 90 by 45 to get 2.
x=\frac{7}{2}
Divide both sides by 2.
