Metoda grafică:
a |-----|
b |-----|-----| }936
c |-----|-----|••6••|
936-6=930
930:5=186 (un segment)
a=186
b=186+186
b=372
c=186+186+6
c=378
Metoda calculelor:
a+b+c=936
b=2a
c=b+6
c=2a+6
a+2a+2a+6=936
5a=936
a=936:5
a=186
b=2a
b=196×2
b=372
c=b+6
c=372+6
c=378
Poți alege tu ce metodă vrei să aplici. Succes! :)
