x - 2y = 5
-3x + 2y = 7
-----------------add
-2x = 12
x = 12/-2
x = -6
-3x + 2y = 7
-3(-6) + 2y = 7
18 + 2y = 7
2y = 7 - 18
2y = - 11
y = -11/2
solution is : (-6,-11/2)...x = -6 and y = -11/2

Answer:
60
Step-by-step explanation:
The part where y resides is an equilateral triangle. That means that all the angles are equal (along with all the sides). Remember that y is in a triangle.
So the three angles of the triangle = 180/3 = 60
That means that y = 60
