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
