va rog frumos si rezolvarea 

Answer 1

[20:(x:40-24)x75x100:15-9980]x40=8x100=800
20:(x:40-24)x75x100:15-9980=800:40=20
20:(x:40-24)x75x100:15=9980+20=10000
20:(x:40-24)x75x100=10000x15=150000
20:(x:40-24)x75=150000:100=1500
20:(x:40-24)=1500:75=20
x:40-24=20:20=1
x:40=24+1=25
x:40=25
x=25x40
x=1000
