17+17+17=51
The number is 17.
The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).
17
It is: 1*17 = 17 which is a prime number

Suppose the number is x Then number diminished by 5 is (x-5) Six times the number diminished by 5 is 6*(x-5) So 6*(x-5) = 72 Divide both sides by 6: (x-5) = 12 Add 5 to both sides: x = 17
