Answer is X= 16 Y= 17

Step by step

The lower straight angle LRN gives us angles 7x, x and 52 that added together equals 180 degrees

So our equation is

7x + x + 52 = 180

Combine like terms

8x + 52 = 180

Subtract 52 from both sides to isolate x

8x + 52 - 52 = 180 - 52

8x = 128

Divide both sides by 8 to solve

x = 16

Now we can solve for y

Straight angle MRP gives us 7x and 4y, which will equal 180 degrees. Our equation is
7x + 4y = 180

We know x = 16

7(16) + 4y = 180

112 + 4y = 180

Subtract 112 from both sides to isolate y

112 - 112 + 4y = 180 - 112

4y = 68

Divide both sides by 4 to solve

4/4 y = 68/4

y = 17
