let H = the height of the ladder.
\n" ); document.write( "let S = the length of each step.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the height of the ladder is 6 feet longer than the length of each step.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "equation for that is H = S + 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ladder has 2 pieces of wood that are as long as the height of the ladder and 6 pieces of wood that are as long as the length of each step.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the total amount of wood is 20 feet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "therefore:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2H + 6S = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since H = S + 6, then:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 * (S + 6) + 6S = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify to get 2S + 12 + 6S = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "combine like terms to get 8S + 12 = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 12 from both sides of the equation to get 8S = 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for S to get S = 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the length of each step is equal to 1 foot.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the height of the ladder is S + 6 = 7 feet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "there are 2 pieces of wood that are 7 feet long each and 6 pieces of wood that are 1 foot long each.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "total amount of wood = 2 * 7 + 6 * 1 = 14 + 6 = 20.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the dimensions of the ladder are 7 feet high by 1 foot wide.\r
\n" ); document.write( "
