But what's wrong with the following logic?

"regular purchase cost - 9 saving =discounted purchase cost "

E.g. 3*15+2*18 - 9 = 3*15(1-x)+2*18(1-y)

45+36-9=45-45x+36-36y

Further we have a system of linear equations, from which we need to find out y

45x+36y=9
-
x+ y=22 /*45
------------------------
0+(-9y)=9-990

y=109
