Answer 1

The correct response is:

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

This step is used to eliminate the fraction in the equation, making it easier to solve for \( x \).

13−2
13 minus 2

2×1
2 times 1

1−15
1 minus 15

15÷4

Answer 3

To determine the first step in simplifying the expression \( 13 - 2(1 - 15) \div 4 \), we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

In this case, the first step involves evaluating the expression inside the parentheses:

1−15

So the correct response is:

1−15
