5\times 3=4k
Variable k cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5k, the least common multiple of k,5.
15=4k
Multiply 5 and 3 to get 15.
4k=15
Swap sides so that all variable terms are on the left hand side.
k=\frac{15}{4}
Divide both sides by 4.
