Nthis lab, you will figure out who was guilty of the classroom food mess by determining which macromolecules are present in the mystery food sample. rephrase this statement as a scientific question you can answer through investigation.

Can we use the process of elimination to prove who was guilty of the classroom food mess.

What macromolecules are present in the mystery food sample?

b would be the right answer

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
