Diferenta a doua numere este 212.Daca imparti un numar la celalalt, obtii catul 8 si restul 2.Sa se afle numerele.
Ma puteti ajuta?

Answer 1

$a-b=212 \\ a:b=8 \ rest \ 2 \to \boxed{a=8b+2 } \\ **********************\\ 8b+2-b=212\\7b+2=212\\7b=212-2\\7b=210\\b=210:7\\\boxed{7=30} \\ \\ a-30=212\\a=212+30\\\boxed{a=242}$

Answer 2

a-b=212
a:b=8 rest 2
a=bx8+2
8b+2-b=212
7b+2=212
7b=212-2
7b=210
b=210:7
b=30
a=30x8+2
a=240+2
a=242
