x+y=180
x=2y-30
2y-x=30
add equation 1 and 3
3y=210
y equals 70°
and x equals 110°
x=2y-30
2y-x=30
add equation 1 and 3
3y=210
y equals 70°
and x equals 110°

angle + supplement = 180, hope you know that
Supplement = x
angle = 2x - 30
so
2x - 30 + x = 180
3x - 30 = 180
3x = 210
x = 70
So supplement is 70
180-70=110
so the angle is 110
Supplement = x
angle = 2x - 30
so
2x - 30 + x = 180
3x - 30 = 180
3x = 210
x = 70
So supplement is 70
180-70=110
so the angle is 110
