Apply the property here to add the two angles

50 + y - 40 = 180
y + 10 = 180
y = 170

$$(y-40°) + 50° = 180°$$

$$y - 40° + 50° = 180°$$

$$y + 10° = 180°$$

$$y = 180° - 10° = 170°$$

Since we have two supplementary angles, we can sum the two angles to 180 and solve for y:

50 + y - 40 = 180

y = 170
