[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 !
