Answer:
x = 290
y = 190
Step-by-step explanation:
11x + 6y = 4330
22x + 5y = 7330
-------------------------------
22x + 12y = 8660
22x + 5y = 7330
===================
(12-5)y = 8660 - 7330
7y = 1330
y = 1330/7 = 190
-----------------------------
11x + 6(190) = 4330
11x + 1140 = 4330
11x = 4330 - 1140
11x = 3190
x = 290
