Answer is x= 15 y= 7

Step by step

The two “x” variable angles are supplementary so combined they will equal 180 degrees

2(5x -5) + (3x -5) = 180

Distribute

10x -10 + 3x -5 = 180

Combine

13x -15 = 180

Add 15 to both sides to isolate variable

13x -15 + 15 = 180 + 15
Combine

13x = 195

Divide both sides by 13 to solve for x

13/13 x = 195/13

x = 15

The two “y” variable angles are supplementary so combined they will equal 180 degrees

5y + 5 + 20y = 180

Combine

25y + 5 = 180

Subtract 5 from both sides to isolate y

25y +5 -5 = 180 -5

25y = 175

Divide both sides by 25 to solve for y

25/25 y = 175/25

y = 7
