Answer:
y = 1
Step-by-step explanation:
Find the slope of the line passing through the points
and 

The slope of the line is equal to

then

X = 15 because the two angle equations are congruent and y = -12 because the two top parallel lines are congruent
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
