Answer:
x = 5, y = 2.
Explanation:
If the figure is a parallelogram then opposite sides are equal and parallel so y = -x + 7 and 2y + 4x = 24.
We can write y = -x + 7 as x + y = 7, so we have:
x + y = 7 (1)
4x + 2y = 24 (2)
Multiply (1) by 2:
2x + 2y = 14
Subtract this from (2):
2x = 10
x = 5.
So from (1):
5 + y = 7
y = 2.
