y=17 x=10

Step-by-step explanation:

so they have equal measures and they’re a linear pair (make a line) and a line is 180° so that would means you can set both equal to 90°

9y-63=90 and 9x=90

so for the first one you subtract 63 from 90 then divide by 9 to get 17

the next one you just divide by 9 to get 10 therefor y=17 and x=9
