[tex]a-b=122 \\ a:b=4 \ r \ 2 \to \boxed{a=4b+2} \\ ******************* \\ 4b+2-b=122 \\ 3b+2=122 \\ 3b= 122-2 \\ 3b= 120 \\ \boxed{b= 40} \\ \\ a-40=122 \\ \boxed{a=162}[/tex]

a-b=122 a÷b=4 rest 2 Folosim formula: D=I×C+R a=b×4+2 4b+2-b=122 3b=122-2 3b=120 b=120÷3 b=40 a=4×40+2=160+2 a=162 162-40=122
