Question

what operation do you perform first when solving \\(\frac{z}{a} = b + c\\) for \\(z\\)?
\\(\circ\\) a. multiply both sides by \\(a\\)
\\(\circ\\) b. add \\(c\\) to both sides
\\(\circ\\) c. divide both sides by \\(b\\)
\\(\circ\\) d. subtract \\(c\\) from both sides

Explanation:

Step1: Isolate \(z\)

The equation is \(\frac{z}{a} = b + c\). To solve for \(z\), eliminate the denominator \(a\) first.

Step2: Apply inverse operation

Multiply both sides by \(a\): \(z = a(b + c)\). This is the first step.

Answer:

a. Multiply both sides by \(a\)
