It's an example of converting something easy into something nearly impossible, and then expressing it obscurely. Behind the veil lies an almost trivial algebra exercise. Although the question doesn't ask for the solution to the exercise, here it is anyway, at no extra cost: -- The difference between (eight times a number) and (twice the number) is (six times the number). -- (Six times the number) is eighteen. -- (the number) is one-sixth of eighteen, or three.
7*(2*x - 16), or maybe 7*| 2*x - 16 |. It depends on if you want to keep the 'difference' to be a positive number.
If you mean the difference between -11 and 2*(-11), then it's 11.

It is 3*n - 5
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
