Answer:
2/3 or 3/2
Step-by-step explanation:
Let x represent the number. The given relation is ...
x +1/x = 2 1/6
x^2 +1 = (13/6)x
6x^2 -13x +6 = 0 . . . . . subtract the right side and multiply by 6
(6x -9)(6x -4)/6 = 0 . . . . factor
(2x -3)(3x -2) = 0 . . . . . . simplify a bit
x = 3/2 or 2/3 . . . . . . . . values of x that make the factors zero
The number is 2/3 or its reciprocal, 3/2.

Answer:
Explanation:
x - 7y = 7
-7y = -x + 7
y = (-1/-7)x + 7/-7
y = (1/7)x - 1
6x - 7y = -28
-7y = -6x - 28
y = (-6/-7)x - 28/-7
y = (6/7)x + 4
