Let's use the variable m to represent the number of books Martha has.
Then we can write the following expression to represent the number Joe has: m + 2
Since the total they have together is 56, we can write the following equation:
Martha + Joe = 56
m + m + 2 = 56
Now we can solve this equation to find the number of books Martha has:
m + m + 2 = 56
2m + 2 = 56
2m + 2 - 2 = 56 - 2
2m = 54
2m/2 = 54/2
m = 27
Martha has 27 books.
Joe will have two more than Martha. Joe will have 29 books.
