That's so loving easy.
7y-10=5y+58
y=34
(Vertical Angles)
7y-10+2x-6=180
x=81
(Some random postulate)
That's wrong, you need to get the Angle, not the X and Y values.
Edit: Lol, since I randomly put that together, it came out weird...
7y-10=5y+58
2y-10=58
2y=68
y=34
7(34)-10
238-10
228
5(34)+58
170+58
228
180-228
-48 = <AMD
