Here are set-ups:
\n" ); document.write( "(1)
\n" ); document.write( "Let \"+a+\" = gallons of 15% alcohol needed
\n" ); document.write( "Let \"+b+\" = gallons of 30% alcohol needed
\n" ); document.write( "given:
\n" ); document.write( "\"+a+%2B+b+=+30+\"
\n" ); document.write( "\"+%28+.15a+%2B+.3b+%29+%2F+30+=+.25+\"
\n" ); document.write( "-------------------------
\n" ); document.write( "(2)
\n" ); document.write( "Let \"+n+\" = number of nickels in box
\n" ); document.write( "Let \"+d+\" = number of quarters in box
\n" ); document.write( "given:
\n" ); document.write( "\"+n+%2B+d+%2B+q+=+85+\"
\n" ); document.write( "\"+n+=+3d+\"
\n" ); document.write( "\"+5n+%2B+10d+%2B+25q+=+625+\" ( in cents )
\n" ); document.write( "
\n" ); document.write( "
\n" );
