Due west is the direction, along the surface of the Earth, that is at right angles to due north, and is on the left side as you look northwards.
157 W + 73 deg west = 230 West. But for longitudes over 180 degrees, the usual convention is to subtract 360 degrees.
230 W - 360 = 140 East

Due west means "directly west," or 270 degrees on a compass.
To determine the meridian (line of longitude) that is 73 degrees west of 157W, just add. You will come up with 230. But, by convention, meridians are only counted to 180 (the Prime Meridian is 0 degrees, and they are counted upward on either side until you get to 180). So 230 degrees West is actually 130 degrees East (360-230).
I know that was probably confusing, but your answer is 130 degrees East.

First add 73 and 157. Subtract your answer from 360 and I believe you get 130 E longitude.
