1 answer:

4 0

This question is quite simple really. They are basically asking you to combine like terms. You have two different figures with the variable y, so you just combine the them. It would then be 3x + 2y. You cannot simplify this equation any further since there is nothing to solve for or anymore like terms to combine.

Round it to the nearest tenth of a percent.

7.2463.. rounded to the nearest tenth is 7.2%
