You can put this solution on YOUR website!
Let j = number that Jill has
Let k = number that Keesha has
given:
(1) j+%2B+k+=+17
(2) j+=+k+%2B+5
---------------
Substitute (2) into (1)
k+%2B+5+%2B+k+=+17
2k+=+12
k+=+6
and
(1) j+%2B+k+=+17
j+%2B+6+=+17
j+=+11
Jill has 11 shells, and Keesha has 6 shells
