Question

multiple-choice question
to solve for y,
divide both sides of the equation by 3
multiply both sides of the equation by 3
subtract 3 from both sides of the equation
add 3 to both sides of the equation
rewatch

Explanation:

Assuming the equation is of the form \( \frac{y}{3}=k \) (where \( k \) is some expression or value), to isolate \( y \), we need to reverse the division by 3. The inverse operation of division by 3 is multiplication by 3. So we multiply both sides of the equation by 3 to solve for \( y \) (e.g., if \( \frac{y}{3}=2 \), multiplying both sides by 3 gives \( y = 6 \)). The other options: dividing by 3 would not isolate \( y \) if it's already divided by 3, subtracting or adding 3 is not the inverse operation for isolating \( y \) in a division - related equation here.

Answer:

B. multiply both sides of the equation by 3
