Question

when solving \\(\frac{k + l}{m} = n\\) for \\(k\\), begin by:
\\(\bigcirc\\) a. adding \\(l\\) to both sides
\\(\bigcirc\\) b. subtracting \\(l\\) from both sides
\\(\bigcirc\\) c. multiplying both sides by \\(m\\)
\\(\bigcirc\\) d. dividing both sides by \\(n\\)

Explanation:

Step1: Identify the goal

Solve for \( k \) in \( \frac{k+l}{m}=n \).

Step2: Eliminate denominator first

Multiply both sides by \( m \): \( k+l = mn \). This is the first step.

Step3: Evaluate options

Option c matches the first step. Other options don’t start correctly.

Answer:

c. Multiplying both sides by \( m \)
