Let x be the number of cows in the herd. Since each cow has 4 legs and 2 eyes, there are 4x legs and 2x eyes in total. Given that there are 84 more legs than eyes, we have 4x = 2x + 84. Solving this equation gives x = 42, so there are 42 cows in the herd.
A frogs eye can be many colours, normally they are brown blue or green
Let the number of cows be x, and the number of birds be y. Since each of them has two eyes, cows have four legs, and birds have two legs, we can create a system o equations: 2x + 2y = 172 4x + 2y = 344 Multiply by -1 the first equation; -2x - 2y = -172 4x + 2y = 344 Add both equations; 2x = 172 Divide by 2 to both sides; x = 86 Substitute 86 for x into the first equation; 2(86) + 2y = 172 172 + 2y = 172 y = 0 Thus, the man has only 86 cows, and no birds.
