Lentilka

Lentilka made 31 pancakes. Eight don't fill with anything, 14 pancakes filled with strawberry jam, and 16 filled with cream cheese. a) How many Lentilka did strawberry-cream cheese pancakes? Maksik ate four strawberry-cream cheese and all pure strawberry pancakes. Mikulaš ate three unfulfilled and all the pure cream cheese pancakes. b) How many pancakes eat Maksik? c) How many pancakes eat Mikulaš?

Correct answer:

a =  7
b =  11
c =  12

Step-by-step explanation:


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

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

Row 2 - Row 1 → Row 2
a = 7
b = 11
a+c = 19

Row 3 - Row 1 → Row 3
a = 7
b = 11
c = 12


c = 12/1 = 12
b = 11/1 = 11
a = 7/1 = 7

a = 7
b = 11
c = 12
