Răspuns:

Explicație pas cu pas:

a + b + c + d + e = 99

c _______

d _______+ 1

e _______ + 2

3 segmente + 1 + 2 = 33

3 segmente + 3 = 33

3 segmente = 33 - 3 = 30

1 segment = 30 : 3 = 10

c = 10

d = 10 + 1 = 11

e = 10 + 2 = 12

_________________________

a + b = 99 - 33 = 66

a ______

b ______+ 2

2 segmente + 2 = 66

2 segmente = 66 - 2 = 64

1 segment = 64 : 2 = 32

a = 32

b = 32 + 2 = 34
