Step-by-step explanation:

x - y + y =  y

 x - y + y    y

  = ---

    x-y      x-y

        y     y

   1 + --- = ---

       x-y   x-y

         1 = 0

Now we know that 1 = 1, so add the following three equations together:

1 = 0

1 = 1

1 = 1

On the right is 1+1, and on the left is 3 ones, and 3 ones make 3.
