\n" ); document.write( "4D + 5C = 652
\n" ); document.write( "5D + 4C = 617
\n" ); document.write( "-------------------------
\n" ); document.write( "Can you do the rest?
\n" ); document.write( "=========================
\n" ); document.write( "1 way to do this is using elimination.
\n" ); document.write( "Multiply eqn 1 by 5 and eqn 2 by 4.
\n" ); document.write( "--------------------
\n" ); document.write( "4D + 5C = 652 times 5 ---> 20D + 25C = 3260
\n" ); document.write( "5D + 4C = 617 times 4 ---> 20D + 16C = 2468
\n" ); document.write( "==========================
\n" ); document.write( "20D + 25C = 3260
\n" ); document.write( "20D + 16C = 2468
\n" ); document.write( "--------------------------- Subtract
\n" ); document.write( "9C = 792
\n" ); document.write( "C = 88
\n" ); document.write( "===========================
\n" ); document.write( "Sub for C in any eqn to find D.\r
