Audrey’s mother bought a large rectangular cake for Audrey’s 13th birthday party. The cake was cut into 32 equal pieces to be shared among Audrey, her school friends, and her two younger brothers. Audrey ate 1/16 of the cake, her friends ate 3/4 of the cake, and her two brothers together ate 1/3 of the remaining pieces of the cake. How many pieces of cake did Audrey’s brothers have?

You'd be well advised to identify the type of problem you're working with.  Is this problem one of direct proportion (as I think it is)?  If so, say so.

If y = -7 when x = -21, then y  = (1/3)x, and (1/3) is the constant of proportion.

A similar truth is that x = 3(y), as -21 = 3(-7)

So, if y=9, x = 3(9) = 27
