Distance vs Displacement

After a displacement of -26 m, a train on a straight track is at the position x_f = 4.0 m. What was the train’s initial position?

x_{i = _____ m}

The initial position of a train is x_i = - 19 m. After a displacement of 17 m, a train on a straight track is at the position x_f = ______ m. Use P for positive and N for negative.
