P is between points A and B. AP=13 and AB=27What is PB?Units

Given the data:
[tex]\begin{gathered} AP=13 \\ AB=27 \end{gathered}[/tex]Since P is between A and B
Then
we can represent this as follow
[tex]\begin{gathered} AB=AP+PB \\ 27=13+x \end{gathered}[/tex]Collecting like terms
[tex]\begin{gathered} x=27-13 \\ x=14 \end{gathered}[/tex]Therefore, PB=x=14
Hence, PB= 14 units
