Shawnece is multiplying both sides of the equation by 7 to "undo" the division of \( x \) by 7 in the original problem.
The original equation is:
\[ \frac{x}{7} - 4 = -6 \]
To isolate \( x \), she first needs to eliminate the \( \frac{x}{7} \) term. By multiplying both sides of the equation by 7, she effectively gets rid of the division by 7. So the correct answer is:
Multiplying both sides by 7 undoes the division of \( x \) by 7 in the original problem.
