Question

in 2 cisterne se afla 792 litri benzina daca se muta 24 l din prima cisterna in a 2 in ambele vor fi cantitati egale ce cantitate contine fiecare

Answer 1

a) |____|+24=>792:2+24
b) |____|-24 =>792:2-24
a+b=792
 a=792:2+24...si b=792:2-24

792:2=396
(396+24)+(396-24)=
=420+372
=792

a=420
b=372

420+372=792
420-24=372+24
396=396
