What is the result of adding these two equations?
-5x-9y=3
5x-9y=-2

Please don't give me credit, but I want to say that;

1. You need a picture attached to this

2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet

3. The width can't be a negative value, so eliminate the negative answers

4. For the second answer, why is there a coma preceding another value? The width can can only be one value

You can add all these elements

Hoped this helped!
