Homework Help: Math

Posted by Sephiroth on Wednesday, December 19, 2007 at 5:10pm.

"Jeremy is cooking using a recipe that requires flour, sugar and water. For each cup of sugar that Jeremy uses, he needs to use two cups of flour. He needs to use 2 1/2 more cups of water than flour. He also needs to use 3 1/2 cups less sugar than water. Find the amount of flour, sugar, and water that Jeremy needs."

I tried the problem and got these three equations:

2f = s
w = f + 2.5
w - 3.5 = s

The problem is (you've probably guessed it by now) that there is no set of matching variables to plug in. I have an exam tommorow and I am entirely lost. Please help.
