e of one apple pie
2 answers:
I'm guessing but not sure, wouldn't it be 7
A= Apple Pies
L= Lemon Pies
3A + 1L = 21
2A + 3 L = 28
Try to get one variable to the negative version of the other. Like this
(-3)3A + (-3)L = (-3)21
2A + 3L = 28
So now, it is:
-9A - 3L = -63
2A + 3L = 28
Combine Terms.
-7A = -35
A = 5
Therefore, One Apple Pie costs $5, and one Lemon Pie costs $6
