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
