9\times 5=16w
Variable w cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 18w, the least common multiple of 2w,9.
45=16w
Multiply 9 and 5 to get 45.
16w=45
Swap sides so that all variable terms are on the left hand side.
w=\frac{45}{16}
Divide both sides by 16.
