5\times 3=3w
Variable w cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5w, the least common multiple of w,5.
15=3w
Multiply 5 and 3 to get 15.
3w=15
Swap sides so that all variable terms are on the left hand side.
w=\frac{15}{3}
Divide both sides by 3.
w=5
Divide 15 by 3 to get 5.
