Let $\"+x+\"$ = ounces of alcohol in 1st solution
\n" ); document.write( " $\"+x+%2F+%28+8+%2B+2+%29+=+.4+\"$
\n" ); document.write( " $\"+x+%2F+10+=+.4+\"$
\n" ); document.write( " $\"+x+=+4+\"$
\n" ); document.write( " $\"+x%2F8+=+4%2F8+\"$
\n" ); document.write( "The concentration
\n" ); document.write( "of the 1st solution is 50% \n" ); document.write( "

\n" );
