Răspuns :
x-nr de copii
4(x+2)-nr de carioci
5(x-2)
4x+8=5x-10
4x-5x=-10-8
-x=-18
x=18
5(18-2)= 5*16=80 de carioci
4(x+2)-nr de carioci
5(x-2)
4x+8=5x-10
4x-5x=-10-8
-x=-18
x=18
5(18-2)= 5*16=80 de carioci
x nr de carioci
x:4 = c rest 2 => x = 4c+2
(x+2):5 = c => x+2 = 5c =>x = 5c-2
4c+2 = 5c-2
c = 4 copii
x = 16+2 = 18 carioci
x:4 = c rest 2 => x = 4c+2
(x+2):5 = c => x+2 = 5c =>x = 5c-2
4c+2 = 5c-2
c = 4 copii
x = 16+2 = 18 carioci
