The total ounces of solution is $\"+60+%2B+15+=+75+\"$ oz
\n" ); document.write( "Let $\"+x+\"$ = ounces of water that evaporate
\n" ); document.write( "---------------
\n" ); document.write( " $\"+15+%2F+%28+75+-+x+%29+=+.6+\"$
\n" ); document.write( " $\"+15+=+.6%2A%28+75+-+x+%29+\"$
\n" ); document.write( " $\"+15+=+45+-+.6x+\"$
\n" ); document.write( " $\"+.6x+=+45+-+15+\"$
\n" ); document.write( " $\"+.6x+=+30+\"$
\n" ); document.write( " $\"+x=+50+\"$
\n" ); document.write( "50 ounces of water evaporate
\n" ); document.write( "check:
\n" ); document.write( " $\"+15+%2F+%28+75+-+50+%29+=+.6+\"$
\n" ); document.write( " $\"+15+%2F+25+=+.6+\"$
\n" ); document.write( " $\"+15+=+.6%2A25+\"$
\n" ); document.write( " $\"+15+=+15+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
