The 2 angles on the left need to equal 180:
3y +5 + 85 = 180
Combine like terms:
3y+90 = 180
Subtract 90 from each side:
3y = 90
Divide both sides by 3:
y = 90 /3
y = 30
Now solve the equation with y:
3(30) +5 = 90+5 = 95
Now the two equations also need to equal 180:
95 + 2x +1 = 180
Combine like terms:
2x + 96 = 180
Subtract 96 from each side:
2x = 84
Divide both sides by 2:
x = 84 /2
x = 42
X = 42, y = 30
The answer is the 3rd choice.
