Answer 1

undeva nua ai inchis paranteza patrata,   dar rezolvi parantezele  intai pana la x

   [31440+1040:(150-2400:120)x20]:x+1000=1080

   [31440+1040:(150-20)x20]:x+1000=1080

   (31440+1040:130x20):x+1000=1080

    (31440+  8x20):x+1000=1080

     (31440+160): x+1000=1080

     31600 :x+1000=1080

      31600:x=1080-1000

      31600:x=80

            x=31600:80

             x=395
