1/2x - 5/6x = 6
6(1/2x) - 6(5/6x) = 6(6)
3x - x = 36
2x = 36
2x/2 = 36/2
x = 36/2
x = 18

Let X be the number...
then 5X/6 - X/2 = 6...
simple algebra from here...
multiply each term by 6 to clear fractions, and get...5X-3X=36 or 2X=36...
hence X=18

(5/6)x - (1/2)x = 6
(5/6)x - (3/6)x = 6
(1/3)x = 6
3 * (1/3)x = 6 * 3
x = 18

Just start with:
5/6 (x) - 1/2 (x) = 6
and solve.

18. Just do the equation, 5/6N - .5N = 6.
