One customer purchases 8 bags of cat food and 2 bags of dog food. The total weight of the purchase is 44 pounds. Another custome
r purchases 5 bags of cat food and 2 bags of dog food. The total weight of the purchase is 35 pounds. A. You write the following system of linear equations to represent this
situation. Is your answer correct?
8x + 2y = 44
5x + 2y = 35
B. Your answer for the next step is 13 79, x = which is incorrect. Explain
the error.
The two equations are similar, because if you multiply the first one by 3 it will be equal to the second one, so when that happens we say that there are infinite solutions.
