Does the product have anything to do with getting the answers?

**drwls**, Tuesday, December 8, 2009 at 5:04pmYou don't need the product info to solve this. You only need to write two equations to solve for two unknowns.

a + b = 5.3

a - b = 1.7

2a = 7

a = 3.5

b = 5.3 - 3.5 = 1.8

The product a*b does satisfy the 6.3 requirement. If it didn't, there would be no solution to all three requirements.

**drwls**, Tuesday, December 8, 2009 at 6:27pmI should not be using algebra for a sixth grade question. It's really the quickest way I know. I hope you were able to follow that.
