Answer 2

x + y + (y - 18) = 180

x = 86

y = 56

Explanation:

The sum of the measures of the angles of a triangle equals 180.

x + y + (y - 18) = 180

x + 2y - 18 = 180

x + 2y = 198

x + 2y = 198

3x - 5y = -22

-3x - 6y = -594

(+) 3x - 5y = -22

----------------------------

-11y = -616

y = 56

x + 2y = 198

x + 2(56) = 198

x + 112 = 198

x = 86
