Răspuns :
a - b = 18 , a > b
a = b · 3 + 2
3b + 2 - b = 18
2b = 18 - 2
2b = 16
b =8
a= 8· 3 + 2 = 26
a = b · 3 + 2
3b + 2 - b = 18
2b = 18 - 2
2b = 16
b =8
a= 8· 3 + 2 = 26
a - b = 18 , a > b
a = b · 3 + 2
3b + 2 - b = 18
2b = 18 - 2
2b = 16
b = 16:2
b =8
a= 8· 3 + 2 = 26
PROBA : 26-8=18
26:8=3 rest 2
