5 units to the left.
Explanation:
They are working against each other. That means you subtract.
32 - 37 = -5
You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.
37 - 32 = 5
The 5 moves in the same direction as the 37
