.
A farm had some cows and goats. 1/5 of the cows and 3/11 of the goats were sold .
There was an equal number of cows and goats left.
If there were 704 cows and goats left, how many were on the farm at first.
~~~~~~~~~~~~~~~~
From the condition, the number of cows left is 704/2 = 352; the number of goats left is the same, 352.
Next, of the cows (what is left) is 352; hence the number of cows initially was = 440;
of the goats (what is left) is 352; hence the number of goats initially was = 484.
