Question

Determinati valoatea lui a:(48+50*100:(28:a+3*2)-14)*((50-4*5)+(143-4*6))egal 42316.

Answer 1

(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)*149= 42316
(48+5000:(28:a+6)-14)= 42268:149
48+5000:(28:a+6)-14= 284
5000:(28:a+6)= 284+14-48
5000:(28:a+6)= 250
28:a+6=20
28:a=14
a=2
