Answer:
x = -2
y = 7
Step-by-step explanation:
x = 12 - 2y
7(12 - 2y) + 4y = 14
84 - 14y + 4y = 14
84 - 10y = 14
10y = 70
y = 7
x = 12 - 2 x 7
x = 12 - 14
x = -2
You mean their sum is 12?
A) x + y = 12
B) x -y = 4 then we add both equations:
2x = 16
x = 8
y = 4
The product will be 40 I believe?

37. we know the perimeter of the Box is 30 and two sides are five each so 30-10 is 20 divided by the other two equal size is 10 .
