Parallel lines e and f are cut by transversal b. what is the value of y?

2x + 18 and 4x - 14 are corresponding angles...they are equal

2x + 18 = 4x - 14
2x - 4x = -14 - 18
-2x = - 32
x = -32/-2
x = 16

so the measure of 4x - 14 = 4(16) - 14 = 64 - 14 = 50

and 4x - 14 and y are supplementary angles that add up to 180 degrees

so 50 + y = 180y = 180 - 50y = 130 <==
