Thats hilarious sorry! :) But anyways you can use either equation: \[xy = 12 \]\[x= \frac{ 12 }{ y }\] OR \[x^2 + y^2 = 40 \]\[x + y = \sqrt{40}\]\[x = \sqrt{40}  y\] **The y and the x can be switched....

Doesn't it depend on how you solved your equation? Also, when I plugged in 2 and 6 for the first problem, I got 12 instead of 12.

Because in B, if you try using ( 2, 6) and ( 2, 6) you already have a problem for the equation below:\[xy = 12\]\[(2)(6) = 12\]\[(2)(6)= 12\]
