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.
