\n" ); document.write( "Equations:
\n" ); document.write( "3d + 300m = 108
\n" ); document.write( "5d + 600m = 193
\n" ); document.write( "--------------------------
\n" ); document.write( "Modify for elimination:

\n" ); document.write( "5d + 600m = 193
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract and solve for \"d\"::
