26 - A group made up of sheep and chickens has a total of 99 legs and heads combined (counted together, so it is not correct to say there are 99 legs and 99 heads, as only the total is known, not the individual count). There are twice as many chickens as sheep. How many animals of each type (sheep and chickens) are in this group? Separate the answers with commas. Example: 'X, Y' (X sheep, Y chickens)
