Answer:

y=23

x=28

Step-by-step explanation:

(5y-4) and 3y make supplementary angles, meaning the two angles add up to 180 degrees

3y and (2x+13) are corresponding angles, so they equal each other

first find y:

5y-4 + 3y = 180

8y -4 = 180

8y = 184

y=23

find x:

3y = 2x+13

substitute the y value:

3(23) = 2x+13

69 = 2x+13

56 = 2x

x=28
