Do-it-in-your-head method: If all animals were horses there would be 4 x 46 ie 184 legs. There is a shortage of 31 legs which means there are 31 cows (and 15 horses).
31 x 3 = 93, 15 x 4 = 60 total 153. Shazam!

On a farm there are horses and three legged cows there are a total of 60 heads and 213 legs how many horses are on the farm?
51 horses of which there are 3 cows with 2 heads and three legs or since there are no 3 legged cows there are 60 horses
On a farm there are horses and chickens There are total of 131 heads and 448 legs How many horses are on the farm?
On a farm there are chickens and three-legged-cows. There are total of 49 heads and 130 legs. How many chickens are on the farm?
On a farm there are horses and three-legged-cows There are total of 90 heads and 337 legs How many horses are on the farm?
If all the animals were horses there would be 360 legs. There is a shortfall of 23 which means 23 cows and therefore 67 horses.
On a farm there are three-legged-cows and horses There are total of 59 heads and 211 legs How many three-legged-cows are on the farm?
If all animals were horses there would be 4 x 59 ie 236 legs. There is a shortage of 25 legs so there are 25 cows (and 34 horses).

You are supposed to: 1) Write two equations, one for the number of heads (express it in terms of the number of cows and horses, which of course are expressed as variables), and one for the number of legs (also expressed as an equation in terms of the number of cows and horses. 2) Solve the two equations simultaneously.
On a farm there are horses and three-legged-cows There are total of 65 heads and 246 legs How many horses are on the farm?
There are 51 horses and 14 sheep (51*4)+(14*3)=246 51+14=65
On a farm there are three-legged-cows and horses There are total of 96 heads and 313 legs How many three-legged-cows are on the farm?
There are 96 heads, so 96 animals. If all were horses, that would be 4 x 96 = 384 legs, but there are only 313 legs, which means there are 384-313 = 71 legs short or 71 cows and 25 horses. Mathematically, let x = horses and y = cows x + y = 96 4x + 3y = 313 multiply first equation by 4: 4x + 4y = 384 4x + 3y = 313 subtract equations y = 71 = cows x = 25 = horses

There are 61 horses and 10 chickens on the farm.
The dairy farm has both cows and chikensThe farm workers counted 50 legs and 18 heads how many cows are in the farm and how many chickens?
7 cows and 11 chickens. Cows have 4 legs. Chickens have 2 legs. (4 legs)(7 cows) + (2 legs)(11 chickens) = 50 legs. 7 cow heads = 11 chicken heads = 18 heads.

27
On a farm there are horses and three-legged-cows There are total of 131 heads and 488 legs How many horses are on the farm?
If all cows were four-legged there would be a total of 4 x 131 ie 524 legs. There are therefore 36 missing legs so there are 95 horses. (4 x 95 + 3 x 36 = 380 + 108 = 488 legs)
On a farm there are three-legged-cows and chickens there are a total of 119 heads and 332 legs how many three-legged-cows are on the farm?
94 three legged cows and 25 chickens.
