\n" ); document.write( "Equations:
\n" ); document.write( "b + h = 100
\n" ); document.write( "4.5b + 20h = 822
\n" ); document.write( "------
\n" ); document.write( "Multiply thru 1st by 200
\n" ); document.write( "Multiply thru 2nd by 10.
\n" ); document.write( "--------
\n" ); document.write( "200b + 200h = 200*100
\n" ); document.write( "45b + 200h = 8220
