Find the value of x and y.

x=15, y=12
x=14, y=11
x=14, y=12
x=15, y=11

So I've already found that x = 14 I just can't figure out how to find y.
Thanks!!

2x + 7 = 3x - 7
3x - 2x = 7 + 7
x = 14

2x + 7 + 12y + 1 = 180
2(14) + 12y + 8 = 180
28 + 12y + 8 = 180
36 + 12y = 180
12y = 180 - 36 = 144
y = 144/12 = 12

x = 14, y = 12
