in a group of ducks and cows , the total number of legs are 32 more than twice the number of heads . find the total number of cows .
"let the number of ducks be d and number of cows be c then , total number of legs = 2 d + 4 c = 2 ( d + 2 c ) total number of heads = c + d given that total number of legs are 32 more than twice the number of heads = > 2 ( d + 2 c ) = 32 + 2 ( c + d ) = > d + 2 c = 16 + c + d = > 2 c = 16 + c = > c = 16 i . e . , total number of cows = 16 answer is c ."
divide(32, const_2)
