If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7

The number is 7.
What is the answer for the problem Seven less than twice a number is the same as one less than the number. What is the number?
This forms an equation which solves nicely: 2x-7 = x-1 x-7 = -1 x = 6
What ia a prime number greatest less than 20 then twice?
The greatest prime number less than 20 is 19. Not sure what "then twice" is unless you are wanting to double it, which becomes 38.
Twice a number increased by 7 is 15?
2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4
The sum of twice the number and 7 less than the number is the difference between -39 and the number?
