The statement of the equation seems a bit unclear because there is either a formatting issue or a typo in the equation you've given. I will assume the equation you meant was one of the following:
1. If the equation is \( x/7 - 47 = -6 \),
Multiplying both sides by 7 is the correct step, as it undoes the division of \( x \) by 7 in the original problem.
2. If the equation is \( x^7 - 47 = -6 \),
Multiplying by 7 would not be the correct step for solving this equation because the term \( x^7 \) is not simply divided by 7.
If the equation is presented as in the first assumption, then the correct response to why Shawn is multiplying both sides by 7 would be:
Multiplying both sides by 7 undoes the division of x by 7 in the original problem.
Shawn is solving the equation
x7−47=−6
One of his steps is to multiply both sides of the equation by 7. Why?
