\n" ); document.write( "D + L = 40 marbles
\n" ); document.write( "D = L + 8
\n" ); document.write( "----------
\n" ); document.write( "Substitute for \"D\" and solve for \"L\"::
\n" ); document.write( "L + 8 + L = 40
\n" ); document.write( "2L = 32
\n" ); document.write( "L = 16 (# Luis has)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"D\":
\n" ); document.write( "D = L + 8
