one - third of his rabbits were female. If x represents the original number of rabbits then,
1/2x - 2 = 1/3(x -2)
Solve this equation to find out what number of rabbits that he had before the sale?

1/2x - 2 = 1/3(x -2)
Multiply by 6 to eliminate all the fractions:
3x - 12 = 2(x - 2)
3x - 12 = 2x - 4
3x - 2x = -4 + 12
x = 8
So... two females of four were sold. Before the sale he had 8 rabbits of which 4 were females (4/8 = 1/2). After the sale he had 6 rabbits of which 2 were females (2/6 = 1/3).

x/6 = 2 - 2/3 = 4/3, so x = 8

As (1/2)x-2=(1/3)(x-2)
or (x-4)/2=(x-2)/3
or 3(x-4)=2(x-2)
or 3x-12=2x-4
or 3x-2x=-4+12
or x=8 ans

3(x-4)/2=x-2
3x-12=2x-4
x=8
