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

Each of these are closed figures formed by straight line segments. Think of fencing in an area (not necessarily a rectangle) using various straight fence sections. The length of each section does not have to be the same.
