You were doing everything correctly! Keep in mind that a straight line is 180 degrees and a triangle has 180 degrees, because I see that some of your questions involve lines.
also remember vertical angles! If you have any specific question, I would be happy to help!
Company Y:
Cost = C
# of minutes = x
C = 0.10x + 10
Company Z:
Cost = c
# of minutes = x
c = 0.20x
Difference in cost = c - C
c - C = 0.20x - (0.10x + 10)
c - C = 0.10x - 10
Hope this helps! :)
