Question

17-{25-[18-16×(x+y):4:2]:7×2-5}:8×3=11​

Answer 1

Răspuns:

Explicație pas cu pas:

-{25-[18--16×(x+y):4:2]:7×2-5}:8×3=11-17=-6

{25-[18-16×(x+y):4:2]:7×2-5}:8=6:3=2

{25-[18-16×(x+y):4:2]:7×2-5}=8*2=16

25-[18-16×(x+y):4:2]:7×2-5=16-20=-4

[18-16×(x+y):4:2]:7=4:2=2

18-16×(x+y):4:2=2*7=14

-16×(x+y):4:2=(14-18) totul  inmultit cu -1

16×(x+y):4:2=4

pt ca 16:4=4 si 4:2=2 ,atunci

x+y=4:2

x+y=2
