Here's what we know:
\n" ); document.write( "B = A + 12
\n" ); document.write( "C = B + 17 (which is A + 29)
\n" ); document.write( "D = C + 23 (which is A + 52)
\n" ); document.write( "E = 207
\n" ); document.write( "A + B + C + D + E = 822
\n" ); document.write( ".
\n" ); document.write( "Let's subtract Ed first.
\n" ); document.write( "822 - 207 = 615
\n" ); document.write( "The equation is now:
\n" ); document.write( "A + B + C + D = 615
\n" ); document.write( "Substitute the values from above, using the As.
\n" ); document.write( "A + (A+12) + (A+29) + (A+52) = 615
\n" ); document.write( "Add
\n" ); document.write( "4A + 93 = 615
\n" ); document.write( "Subtract 93 from each side
\n" ); document.write( "4A = 522
\n" ); document.write( "Divide each side by 4
\n" ); document.write( "A = 130.5
\n" ); document.write( ".
\n" ); document.write( "therefore B = 142.5, C = 159.5, D = 182.5
\n" ); document.write( ".
\n" ); document.write( "Let's add them together to prove it.
\n" ); document.write( "130.5 + 142.5 + 159.5 + 182.5 + 207 = 822
\n" ); document.write( "Success!
\n" ); document.write( " \n" ); document.write( "
\n" );
