Answer 1

Răspuns:

Explicație pas cu pas:

[ 48+50x100:( 28:a+6) -14] x [ (50-20)+143-24] =42.316

[48+50x100:(28:a+6 )-14] x (30+119)=42.316

[ 48+50x100: ( 28:a+6) -14=42.316:149

[ 48+50x100:( 28:a+6) -14= 284

48+50x100:( 28:a+6)=284+14

48+50x100:( 28:a +6) = 298

50x100:(28:a+6)=298-48

50x100:( 28:a+6) = 250

100:(28:a+6)=250:50

100:(28:a+6)=5

28:a+6=100:5

28:a+6=20

28:a=20-6

28:a= 14

a= 28:14

a= 2
