Let \"w\"= cups of water he uses
\n" ); document.write( "\"30+-+w\"= cups of lemon juice he uses
\n" ); document.write( "given:
\n" ); document.write( "\"w%2F%2830-w%29+=+4%2F1\"
\n" ); document.write( "Multiply both sides by \"30+-+w\"
\n" ); document.write( "\"w+=+4%2A%2830+-+w%29\"
\n" ); document.write( "\"w+=+120+-+4w\"
\n" ); document.write( "\"5w+=+120\"
\n" ); document.write( "\"w+=+24\"
\n" ); document.write( "\"30+-+w+=+6\"
\n" ); document.write( "Roger needs 24 cups of water and 6 cups of lemon juice
\n" ); document.write( "
\n" );
