4 bread loafs, 1 pound of meat, 3 pounds of cheese

Step-by-step explanation:

Let loaf of bread be b, meat be m and cheese be c

Based on the given, we have following equations:

b + m + c = 8c = 3mb + 4m + 3c = 17

Subtract the first equation from the third and substitute c with m:

b + 4m + 3c - (b + m + c) = 17 - 83m + 2c = 93m + 2(3m) = 99m = 9m = 1

Then

c = 3*1 = 3b = 8 - (1 + 3) = 4
