Answer 2

The equation that can be used to find the width of the the piece of paper is 3.5 + w = 11.

Let the width of the piece of paper be represented with w inches.

Let the length of of the piece of paper be represented with this expression: 3.5 inches + w inches = 11 inches

In order to determine the value of the width, make w inches the subject of the formula in the above equation. To make w the subject of the formula, combine similar terms together
