Shawnece is solving the equation \( x/7 - 4 = -6 \) (assuming you meant \( x/7 \) instead of \( x7 \)). Based on the given equation, the most accurate reasoning for multiplying both sides by 7 is:
Multiplying both sides by 7 undoes the division of \( x \) by 7 in the original problem.
This is because the original equation likely involves a division of \( x \) by 7, and multiplying both sides by 7 will help eliminate that division, allowing her to isolate \( x \).
