Question

1. in the formula $\frac{j-k}{l}=m$, to solve for $j$, you initially:

a. divide both sides by $m$
b. multiply both sides by $l$
c. subtract $k$ from both sides
d. add $k$ to both sides

Explanation:

Step1: Analyze the target variable

We need to isolate $j$ in $\frac{j-k}{l}=m$.

Step2: Eliminate the denominator first

To remove the $l$ dividing the left side, multiply both sides by $l$:
$\frac{j-k}{l} \times l = m \times l$
Simplifies to: $j - k = ml$

Step3: Confirm initial step

The first operation to start isolating $j$ is multiplying by $l$.

Answer:

b. Multiply both sides by $l$
