Set it up this way:
8n + 7 = 2n
Take 7 away from each side.
8n = 2n - 7
Take 2n away from each side
6n = -7
Divide each side by 6
n = -7/6
To check the answer, replace the n's with -7/6.
8 X -7/6 + 7 = 2 X -7/6
-56/6 + 42/6 = -14/6
-14/6 = -14/6

What is the difference between eight times a number and twice the number is eighteen?
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.
