\(5.\left(x-1\right)-206=2^4.4\\ \Rightarrow5.\left(x-1\right)-206=16.4\\ \Rightarrow5.\left(x-1\right)-206=64\\ \Rightarrow5.\left(x-1\right)=270\\ \Rightarrow x-1=54\\ \Rightarrow x=55.\)

5.(\(x-1\)) - 206 = 2⁴.4

5.(\(x-1\))  - 206 = 64

5.(\(x-1\))            = 64 + 206

5.(\(x-1\)) = 270

    \(x-1\)   = 270 : 5

    \(x-1\)   = 54

    \(x=55\)
