Lentilka

Lentilka made 31 pancakes. 8 don't fill with anything, 14 pancakes filled with strawberry jam, 16 filled with cream cheese.

a) How many Lentilka did strawberry-cream cheese pancakes?

Maksik ate 4 of strawberry-cream cheese and all pure strawberry pancakes. Mikulaš ate 3 unfulfilled and all the pure cream cheese pancakes.

b) How many pancakes eat Maksik?
c) How many pancakes eat Mikulaš?

Correct result:

a =  7
b =  11
c =  12

Solution:

(14-a)+a+(16-a)=31-8
b= 4+(14-a)
c = 3+(16-a)

a = 7
a+b = 18
a+c = 19

a = 7
b = 11
c = 12
