Answer:
y = 9, x = -2
Step-by-step explanation:
1. (9y+4) and (11y-14) are the same size angle, so you can set them equal to each other:
9y+4=11y-14
2. Solve for y:
4=2y-14
18=2y
9=y
3. (3x+28) and 63 together are opposite to (9y+4) so you can set them equal to each other:
(3x+28)+63=(9y+4)
4. You know that y=9, so plug in 9 for y and solve for x:
3x+28+63=9(9)+4
3x+91=85
3x=-6
x=-2
