Answer:
-2-
Explanation:
I broke up the fractions so that it is easier.
- - - = ( - ) - ( + ) - ( + ) - ( - )
Now I remove the brackets. One plus and one minus make one minus and two minus makes one plus.
( - ) - ( + ) - ( + ) - ( - ) = - - - - - - +
Remove redundancies. ( - = 0)
- - - - - - + = - -
Simplify the fractions.
- - = -2-
