21x3 = 63
Let the amount of shells collected by Aaron be

and the amount of shells collected by Maria be

respectively. Then the following system of equations should be solved:

First of all, express

out of first equation:

Then, replace

in second equation with found expression and solve it:



Finally, replace

in first equation with found value and solve it too:


So, Aaron has found
7 shells while Maria has found
21.
