DOUGH           PRICE      QUANTITY       QUANTITY
                            Ernie         Bert     
Choc. Chip       c           8              1
Sugar            z          12              4
REVENUE                    364             93

system%288c%2B12z=364%2Cc%2B4z=93%29

(Not the only way but) The first equation, for Ernie, should be simplified first.
system%282c%2B3z=91%2Cc%2B4z=93%29
