You can put this solution on YOUR website!
Let $\"+w+\"$ = ml of water to be used
\n" ); document.write( "Let $\"+x+\"$ = ml of 34% saline solution to be used
\n" ); document.write( " $\"+.34x+\"$ = salt in 34% solution
\n" ); document.write( "---------------------------
\n" ); document.write( "(1) $\"+.34x+%2F+17+=+.12+\"$
\n" ); document.write( "(2) $\"+x+%2B+w+=+17+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "(1) $\"+.34x+=+.12%2A17+\"$
\n" ); document.write( "(1) $\"+.34x+=+2.04+\"$
\n" ); document.write( "(1) $\"+x+=+6+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+6+%2B+w+=+17+\"$
\n" ); document.write( "(2) $\"+w+=+11+\"$
\n" ); document.write( "---------------
\n" ); document.write( "6 ml of 34% solution is needed\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
