To start, we should define our variables
E= amt of hats Elena has
F= amt of hats Fran has
If Elena has 2 fewer hats than Fran, E= F-2
If Elena and Fran together have 14 hats, we can represent this as
E+F=14
by substituting F-2 for E, we can add our variables
F-2+F=14
2F-2=14
+2 +2
2F=16
divide each side by 2
F=8
Now that we know F=8, we can substitute this into our equation for Elena's hats
E= F-2
E= 8-2
E=6
So Elena has 6 hats and Fran has 8
