1. ????,
   ???? – $\frac{????}{????}$ = $\frac{????}{????}$ + $\frac{????}{????}$

   ???? – $\frac{????}{????}$ = $\frac{????}{????}$ 

   ???? = $\frac{????}{????}$ + $\frac{????}{????}$

   ???? = ????

   ????,
   ???? + $\frac{????}{????}$ = $\frac{????}{????}$ – $\frac{????}{????}$

   ???? + $\frac{????}{????}$ = $\frac{????}{????}$

   ???? =  $\frac{????}{????}$ – $\frac{????}{????}$

   ???? = $\frac{????}{????????}$

2. a , x- 1/6 = 1/2+ 1/3

        x- 1/6 = 5/6

         x         = 5/6 + 1/6

          x         = 1

   b , x+1/8 = 1/2- 1/3

       x+1/8    = 1/6

        x             = 1/6 – 1/8

        x               = 1/24
