\(\left[\left(7+0,004.x\right):0,9\right]:24,7-12,3=77,7\)
\(\left[\left(7+0,004.x\right):0,9\right]:24,7=77,7+12,3\)
\(\left[\left(7+0,004.x\right):0,9\right]:24,7=90\)
\(\left[\left(7+0,004.x\right):0,9\right]=90.24,7\)
\(\left[\left(7+0,004.x\right):0,9\right]=2223\)
\(\left(7+0,004.x\right)=2000,7\)
\(0,004.x=2000,7-7\)
\(0,004.x=1993,7\)
\(x=1993,7:0,004\)
\(x=498425\)
Vậy \(x=498425\).
