Question

Kent multiplies both sides of the equation below by an expression.

k+12/k=8

Then he moves all the terms to one side of the equal sign in the resulting equation. Which equation must he solve now?

Explanation:

Answer 2

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
