Let x = distance between P and T
Points of 2x distance from T will be T - 2x and T + 2x. Thus, 2.

2 Points.
First - left of T with distance equivalent to PT.
Second - between PT with distance PT/3 from P.

Consider two possible cases below:

In both cases TX = 2*PX.

Hope it's clear.

Thats 2.

P is the midpoint btw T and starting point of line L

so 2 (p--t) = distance between T and Starting point of L

so thus T is the midpoint of the line and have two possible points with that distance

well, an easy one. the point can be to the left of point P and to the right of point P. so we must have 2 numbers.
