Answer:
y=105
x=7
one side of the line equals 180
therefore it is impossible for y to not equal 105 as that would just not make sense. i don't know how to explain this better but its basic geometry rules.
as for x you take 180-105 which gets you to 75 which is the angle degrees of y but is not the value for the variable of y itself.
if 75=y then
75=14x-23
98=14x
x=7
