Answer:

Step-by-step explanation:
can be solved by just multiplying the numerators together and the denominators together
2 * 3 = 6 and 5 * 4 = 20 so the answer would be 
This simplifies to

Answer:

Step-by-step explanation:

The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)
Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k
Simplifying,
-7k + 12 = 0
Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7
