The sum of three number is 27 the second number is 1 less than the first and the third is twice the first number what is the numbers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Let x be the first number.
Then the second is (x-1) and the third is 2x.

An equation is

x + (x-1) + 2x = 27,   or

4x - 1 = 27  --->  4x = 27+1 = 28  --->  x = 28%2F4 = 7.

Answer. The numbers are 7, 6 and 14.
