Raising rabbits. Before Roland sold two female rabbits,
half of his rabbits were female. After the sale, only onethird
of his rabbits were female. If x represents his original
number of rabbits, then

1
2
x 2
1
3
(x 2).
Solve this equation to find the number of rabbits that he
had before the sale.

I can't read your post.
If x = original number of rabbits, then
(1/2) x = # female rabbits and
(1/2) x = # male rabbits.

Then if Roland sold 2 female rabbits, the number female rabbits now is (1/2)x -2 and that = (1/3)x
So (1/2)x -2 = (1/3)x. Solve for x.
I obtained 12 for the original number of rabbits. Check my thinking. Check my work.
