Question

what is the first operation to perform when solving $\frac{b + c}{d} = e$ for $b$?

a. divide both sides by $e$

b. add $c$ to both sides

c. subtract $c$ from both sides

d. multiply both sides by $d$

Explanation:

Step1: Isolate numerator

To solve for \(b\), first eliminate the denominator \(d\). Multiply both sides by \(d\):
$$\frac{b+c}{d} \times d = e \times d \implies b + c = ed$$
This is the first step, so the operation is multiplying both sides by \(d\).

Answer:

d. Multiply both sides by \(d\)
