13−2
13 minus 2

2×1
2 times 1

1−15
1 minus 15

15÷4

Answer 2

Shawn multiplies both sides of the equation by 7 to eliminate the division by 7 that is applied to \( x \). This step is necessary to isolate \( x \) and solve the equation. Therefore, the correct response is:

**Multiplying both sides by 7 undoes the division of x by 7 in the original problem.**

Answer 3

To simplify the expression \( 13 - 2(1 - 15) \div 4 \), the first step should be to evaluate the expression inside the parentheses, which is \( 1 - 15 \).

So, the correct response is:

**1−15** (1 minus 15)
