Răspuns :
a x b = 634
( a + 10 ) x b = 864
a x b + 10 x b = 864
624 + 10 x b = 864
10 x b = 864 - 624
10 x b = 240 ⇒ b = 240 : 10 ⇒ b = 24
a = 624 : 24 ⇒ a = 26
Raspuns: 26; 24 → cele doua numere
axb=624 ; (a+10)xb=864, axb+10xb=864, inlocuim axb ⇒624+10xb=864, 10xb=240
b=240 : 10 = 24, a= 624 : 24 = 26
