A-b=2995
a-2995=218
a=218+2995
a=3213
3213-b=2995
b=3213-2995
b=218
a=3213
b=218

A-b=2995
(a+b)-(a-b)=218
(a+b)-2995=218
(a+b)=2995+218
a+b=3213
a=2995+b.
Acum il inlocuim pe a in propozitia matematica de mai sus:
(2295+b)+b=3213
2295+2b=3213
2b=3213-2295
2b=218
b=218:2
b=109
a=109+2995
a=3104 
raspuns: cele 2 nr. sunt: a=3104 si b=109
Verificare: a-b=2995 atunci 3104-109=2995; suma lor minus 2995= 218, adica (3104+109)-2995=3213-2995=218.
