Answer:
See explanation
Step-by-step explanation:
There are three possible cases:
1. Point N lies between M and P, then MN + NP = MP. Consider needed difference:

2. Point N lies to the right from point P, then MP + PN = MN. Consider needed difference:

3. Point N lies to the left from point M, then NM + MP = NP. Consider needed difference:

The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.
Answer:
19
Step-by-step explanation:
Matt ended up with 26.
We reverse the steps he did to get the original number that both people thought of.
26 / 2 = 13
13 - 7 = 6
6 is the original number.
Tikka did the same operations but in the reverse order so...
6 X 2 = 12
12 + 7 = 19
