    Hello, mommyhorse94!

    Did you make a sketch?


    P is between M and N.

    MP \:=\: 2b-7,\;\;PN \:=\:8b,\;\;MN = 43

    Find the value of b and MP.
    Code:
          : - - - - -  43  - - - - - :
          M        P                 N
          *--------*-----------------*
          :  2b-7  : - - - 8b  - - - :

    We have: . (2b-7) + 8b \;=\;43


    Can you finish it now?
