Answer:
x=24 y=15
Explanation:
Alternate exterior angle
6x-7=8y+17
(8y+17) + (3x-29) = 180
(3x-29) + (6x-7)= 180
combine like terms solving for x first because it's easier
9x-36=180
add 36 to both sides
9x=216
divide both sides by 9 to get x by itself
x=24
now you know what x is plug it in for your choice of equations to solve for y
6(24)-7=8y+17
144-7=8y+17
137=8y+17
subtract 17 from both sides
120=8y
divide both sides by 8
15=y
(8y+17) + (3(24)-29) = 180
8y+17+72-29=180
combine like terms
8y+60=180
subtract 60 from both sides
8y=120
divide by 8 on both sides
y=15
