$\huge\bigstar\sf\pink{Answer:}$

We know that here it is given that

x-2y=30

So we can rearrange it and write

x = 30 + 2y. (1)

And Angle X and Y are forming Linear pair

x+y=180........2

So put 1 in 2

30+2y+y=180

30+3y=180

3y=180-30

3y=150

y=50

Again put

y=50 in equation 1

To get

x-100=30

x=130

So x=130

y=50
