Hi\r
\n" ); document.write( "\n" ); document.write( "S + D = 46\r
\n" ); document.write( "\n" ); document.write( "S = 2D + 4\r
\n" ); document.write( "\n" ); document.write( "We now have two simultaneous equations. I am going to say\r
\n" ); document.write( "\n" ); document.write( "S = - D + 46
\n" ); document.write( "S = 2D + 4\r
\n" ); document.write( "\n" ); document.write( "Ok so\r
\n" ); document.write( "\n" ); document.write( "46 - D = 2D + 4
\n" ); document.write( "46 -4 = 2D + D
\n" ); document.write( "42 = 3D
\n" ); document.write( "42/3 = D
\n" ); document.write( "14 = D\r
\n" ); document.write( "\n" ); document.write( "Now we have to work out S\r
\n" ); document.write( "\n" ); document.write( "S = 2D + 4
\n" ); document.write( "
\n" ); document.write( "So\r
\n" ); document.write( "\n" ); document.write( "S = 2 x 14 + 4
\n" ); document.write( "S = 32\r
\n" ); document.write( "\n" ); document.write( "Dave is 14
\n" ); document.write( "Sam is 32\r
\n" ); document.write( "\n" ); document.write( "Hope this helps\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
