Răspuns :
a+b=35
a=4b
4b+b=35
5b=35
b=7 jetoane are primul copil
a+7=35
a=35-7
a=28 jetoane are al2lea copil
(35:5)x4=7x4=28
a=4b
4b+b=35
5b=35
b=7 jetoane are primul copil
a+7=35
a=35-7

(35:5)x4=7x4=28
a |-------|--------|--------|--------|
b |-------| } 35.
35:5 = 7 (b)
7× 4 = 28 (a).
verificare: 28 + 7= 35.
b |-------| } 35.
35:5 = 7 (b)
7× 4 = 28 (a).
verificare: 28 + 7= 35.
