Answer 1

Sper ca te-am ajutat. Daca nu ai inteles ceva poti sa ma intrebi , sau daca am gresit ceva sa imi zici.

Answer 2

[48+50•100:(28:a+3•2)-14]•[(50-4•5)+(143-4•6)]=42316

[48+5000:

(28:a+6)-14]•[(50-20)+(143-24)]=42316

[48+5000:(28:a+6)-14]•(30+119)=42316

[48+5000:(28:a+6)-14]•149=42316

[48+5000:(28:a+6)-14]=42316:149

48+5000:(28:a+6)-14=284

48+5000:(28:a+6)=284+14

48+5000:(28:a+6)=250

28:a+6=5000:250

28:a+6=20

28:a=20-6

28:a=14

a=28:14

a=2

Sper să fie bine, succes !
