two unknowns usually means two equations\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"sold 495 hamburgers today\" ___ c + w = 495\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"The number sold with cheese was 6 less than twice the number sold without cheese\" ___ c = 2w - 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ (2w - 6) + w = 495\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for w, then substitute back to find c
\n" ); document.write( "
