Answer:

x = 21

y = 60

Explanation:

We assume the marks are angle measures.

The angles of a linear pair are supplementary:

(3x +5) +(6x -14) = 180

9x -9 = 180 . . . . simplify

9x = 189 . . . . . . add 9

x = 21 . . . . . . . divide by 9

__

At parallel lines, corresponding angles are congruent.

y +8 = 3x +5 = 3(21) +5 = 68

y = 60 . . . . . subtract 8
