You can put this solution on YOUR website!
the concentration of the 1st solution is:
\n" ); document.write( " $\"+15+%2F+%28+15+%2B+45+%29+=+15%2F60+\"$
\n" ); document.write( " $\"+15%2F60+=+.25+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "Let $\"+x+\"$ = ml of HCL in the 2nd solution
\n" ); document.write( " $\"+x+%2F+%28+x+%2B+132+%29+=+.25+\"$
\n" ); document.write( " $\"+x+=+.25%2A%28+x+%2B+132+%29+\"$
\n" ); document.write( " $\"+x+=+.25x+%2B+33+\"$
\n" ); document.write( " $\"+.75x+=+33+\"$
\n" ); document.write( " $\"+x+=+44+\"$
\n" ); document.write( "------------
\n" ); document.write( "The 2nd solution must contain 44 ml of HCL
\n" ); document.write( "------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+x+%2F+%28+x+%2B+132+%29+=+.25+\"$
\n" ); document.write( " $\"+44+%2F+%28+44+%2B+132+%29+=+.25+\"$
\n" ); document.write( " $\"+44+%2F+176+=+.25+\"$
\n" ); document.write( " $\"+44+=+.25%2A176+\"$
\n" ); document.write( " $\"+44+=+44+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
