Answer:
x = 11
y = 6
Step-by-step explanation:
as 6x - 16 = 4x +6 , (vertically opposite angles)
bringing like terms to one side we get,
2x = 22
x = 11
6x-16 + 8x + 7y = 180 (straight angle)
bringing like terms to one side we get,
14x +7y = 196
subs value of x we get,
154 + 7y = 196
bringing like terms to one side we get,
7y = 42
y = 6
