3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
The question is asking to calculate how many square inches of gift wrap will be needed to cover a box that is 4 in x 6 in x 6 in x 2 in, base on my further research, I would say that the answer would be 88 in^2. I hope that you are satisfied with my answer and feel free to ask for more
