2. 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?
