The correct response is:
Multiplying both sides by 7 undoes the division of x by 7 in the original problem.
This is because the equation starts with \( \frac{x}{7} \), and multiplying both sides by 7 will isolate \( x \).
Shawn is solving the equation

One of his steps is to multiply both sides of the equation by 7. Why?
