The sum of three natural number is 15.
\n" ); document.write( "a + b + c = 15
\n" ); document.write( " The second number is 1 more than the first number.
\n" ); document.write( "b = a + 1
\n" ); document.write( " The sum of the first and third number is equal to twice the second number.
\n" ); document.write( "a + c = 2b
\n" ); document.write( ":
\n" ); document.write( "In the first equation replace a + c with 2b
\n" ); document.write( "2b + b = 15
\n" ); document.write( "b = 15/3
\n" ); document.write( "b = 5
\n" ); document.write( "then
\n" ); document.write( "b = a + 1
\n" ); document.write( "a = 4
\n" ); document.write( "I'll let you find c\r
