d + q = 57
\n" ); document.write( "q = 57 - d
\n" ); document.write( "10d + 25q = 1200
\n" ); document.write( "---
\n" ); document.write( "10d + 25q = 1200
\n" ); document.write( "10d + 25(57 - d) = 1200
\n" ); document.write( "10d + 1425 - 25d = 1200
\n" ); document.write( "15d = 225
\n" ); document.write( "---
\n" ); document.write( "d = 15
