There are 65 more pottery fragments than shell beads. What system of linear equations will represent this scenario?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let x = the number of pottery fragments 
and y = the number of shell beads.

Then

x + y = 87,
x = y + 65.

or (which is the same)

x + y = 87,
x - y = 65.
