three times a number decreased by eleven
It is 5n - 8 <= 2n + 10
Two twenty-seven times or twenty-seven twice, three eighteen times or eighteen thrice, and six nine times or nine six times.
4*(2x + 8) = 32
twice the difference of three times a number and eight

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.
twice a number means a number times 2
