Let $\"j\"$ = number that Jill has
\n" ); document.write( "Let $\"k\"$ = number that Keesha has
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"j+%2B+k+=+17\"$
\n" ); document.write( "(2) $\"j+=+k+%2B+5\"$
\n" ); document.write( "---------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( " $\"k+%2B+5+%2B+k+=+17\"$
\n" ); document.write( " $\"2k+=+12\"$
\n" ); document.write( " $\"k+=+6\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"j+%2B+k+=+17\"$
\n" ); document.write( " $\"j+%2B+6+=+17\"$
\n" ); document.write( " $\"j+=+11\"$
\n" ); document.write( "Jill has 11 shells, and Keesha has 6 shells
