I graphed it, and made sure for all integers x from 11 - 20 (10 doesn't work) that there is no integer B such that 1/10 - 1/x = 1/B

I counted
(20, 20)

(35, 14)

(30, 15)

(60, 12)

(110, 11)

(11, 110)

(12, 60)

(15, 30)

(14, 35)

Simplify to... 3x^2 - kx + 33 = 0

Then in Desmos, graph 

3x^2 - kx + 33 = 0

and

k = 0

Click on k = 0 and set the Step to 1

Change the range from "-10 to 10" to "0 to 25"

let the slider play from 25 to 0 and find the first one that has no line shown on it

Just realized the answer. I got confused on whether (35, 14) and (14, 35) should be counted as 1 or 2
