Please Help!

-$\frac{1}{2}$ + x + $\frac{2}{3}$ = -$\frac{5}{6}$

Find what x equals.
Please show your work!

Or try to solve this!

$\frac{1}{6}$ + $\frac{1}{x}$ = -$\frac{5}{6}$

I think the answer is: x = 1. Mr. Hui is this answer right?

I am pretty sure that x=2 or -2 try putting 2 instead of the variable which is 2 over 1 and it works __________________ impossible is just a word used by people who are too afraid to do something themselves. In reality there's no such thing as impossible.

(1/6) + (1/x) = -5/6

First get common denominators for the left hand side.

x/(6x) + 6/(6x) = -5/6

(x + 6)/(6x) = -5/6

Then cross multiply.

-30x = 6x + 36
-36 = 36x
-1 = x

Thank you Mr. Hui and MAS1!
