Question

1/4•{1/4•[1/4•(1/4•x+1)+4]+1}+4=5. Îmi poate da cineva un raspuns rapid va rog

Answer 1

Răspuns:

1/4·{1/4·[1/4·(1/4·x+1)+4]+1}+4=5

1/4·{1/4·[1/4·(x/4+1)+4]+1}=5-4

1/4·{1/4·[1/4·(x/4+1)+4]+1}=1

{1/4·[1/4·(x/4+1)+4]+1}=4

1/4·[1/4·(x/4+1)+4]=4-1

1/4[1/4(x/4+1)+4]=3

1/4(x/4+1)+4=12

1/4(x/4+1)=8

x/4+1=32

x/4=31

x=4·31

x=124
