In a flock of black and white sheep 2 out of 5 are white if there are 8 more black sheep than white how many sheep are there?

Let's denote the number of white sheep as W and the number of black sheep as B. We are given that 2 out of 5 sheep are white, so W = 2/5(W + B). We are also told that there are 8 more black sheep than white sheep, so B = W + 8. By substituting the second equation into the first equation, we can solve for the total number of sheep in the flock.
