Let's begin by getting rid of the numbers in the denominators. Do that by multiplying every term on both sides of the equation by 5*6 (or 30) to get:
.
.
In the two terms with numerical denominators cancel the denominator with the corresponding number in the term's numerator:
.
.
This makes the equation become:
.
.
Subtract 5 from both sides to get rid of the 5 on the left side:
.
.
Multiply out the numerator on the left side:
.
.
Multiply both sides by K to eliminate the denominator on the left side and get:
.
.
That's the value of K that will satisfy the original equation.
.
Hope this helps you to understand the problem.
