Question

ajutatima va rog 15:[11-(7ori5-9ori9:x:3):8+2x4]ori3=3 va rog nu gresiti si verificati va rog din suflet

Answer 1

15:[11-(7×5-9×9:x:3):8+2×4]×3=3
15:[11-(35-81:x:3):8+8]=1
11-(35-81:x:3):8+8=15
11-(35-81:x:3):8=15-8
11-(35-81:x:3):8=7
(35-81:x:3):8=11-7
(35-81:x:3):8=4
35-81:x:3=4×8
35-81:x:3=32
81:x:3=35-32
81:x:3=3
81:x=3×3
81:x=9
x=81:9
x=9
