Răspuns :
Notam cele 2 numere cu a,b
a*b=59220
(a+19)*b=77080
a*b+19*b=77080
77080-59220=17860
a=17860/19
a=940
b+19=77080/940
b+19=82
b=82-19
b=63
/ inseamna fractie sau impartire.

Notam cu a si b numerele
a x b =59 220
(a+19) x b =77 080
a×b +19×b =77 080
59 220 +19×b = 77 080
19×b= 77 080 - 59 220
19×b=17 860
b= 17 860 :19
b= 940
59 220 : 940 =63 (a)
Verific: 63 × 940 =59 220
a x b =59 220
(a+19) x b =77 080
a×b +19×b =77 080
59 220 +19×b = 77 080
19×b= 77 080 - 59 220
19×b=17 860
b= 17 860 :19
b= 940
59 220 : 940 =63 (a)
Verific: 63 × 940 =59 220
