Answer:
87
Step-by-step explanation:
the number sequence is upside down
Set 5x=3x+50 because they are alternate exterior angles. Solve for x and you should get x=25
Next step, plug in the x value for 5x. So 5*25=125. Set y+12=125 since they are vertical angles which are congruent. Solve for y and you get y=113

9x = 0, x = 0
x + 6 = 0, x = -6
The solution: x = 0, -6
