Question

18*[x-16]=18

 

Answer 1

Ta có: 18(x - 16) = 18

=> (x - 16) = 1

=> \(\orbr{\begin{cases}x-16=1\\x-16=-1\end{cases}\Rightarrow\orbr{\begin{cases}x=17\\x=15\end{cases}}}\)

                                        Vậy x = 15 , x = 17

Answer 2

18x(x-16)=18

      x-16 =18:18

      x-16= 1

       x   = 1+16

       x    =17

Vậy x=17

Answer 3

18*(x-16)=18

(x-16)     =18:18

(x-16)     =1

x           =1+16

X           17
