A flight attendant packed two rectangular suitcases for her trip to Hawaii. Both hold the same volume of clothes. Her brown suitcase has a length of 3y, a width of 2y – 1, and a height of y. Her black suitcase has a length of 4y − 2 and a width of y. What...

The volume of each rectangular suitcase in the problem above can be found using the formula V=lwh. Substitute the rational expressions from the original problem to set up an equation. The volume for the first suitcase would be: V = lwh V= (3y)(2y – 1)() T...

The answer is y=h. But I don't know how to find it.

It told me the answer and explained how to get it but I don't understand it.

First, it told me to do this for the first suitcase by finding volume, V = lwh. V= (3y)(2y – 1)(y/3)

Correct.

See, this is what I figured as well, but the instructions say to originally change the y, the ones by themselves, to a y/2 for the second and y/3 for the first. I don't understand why it would change them.
