\n" ); document.write( "=========================
\n" ); document.write( "Let n = the 1st number
\n" ); document.write( "Then the 2nd number = n - 5
\n" ); document.write( "And the 3rd number = 2n - 8
\n" ); document.write( "Their sum = 43:
\n" ); document.write( "n + (n-5) + (2n-8) = 43
\n" ); document.write( "4n - 13 = 43
\n" ); document.write( "4n = 56
\n" ); document.write( "n = 14
\n" ); document.write( "So the numbers are 14, 9 and 20
\n" ); document.write( " \n" ); document.write( "
