Answer:
2
Step-by-step explanation:
The solutions are ...
p +m|x +n| = k . . . . . given
m|x +n| = k -p . . . . . . subtract p
|x +n| = (k -p)/m = (p -k)/-m . . . . . . must have (p-k)/-m ≥ 0
x = -n ± (p -k)/-m
For the given conditions, m < 0, p > k, we are guaranteed that (p-k)/-m > 0, so there are 2 solutions.
