\(60-3\times(x - 2)=51\)

\(3\times(x-2)=60-51\)

\(3\times(x-2)=9\)

\(x-2=9:3\)

\(x-2=3\)

\(x=3+2\)

\(x=5\)

60-3(x-2)=51

3(x-2)=60-51=9

x-2=9:3=3

x=3+2

x=5

\(60-3\left(x-2\right)=51\)

=> \(3\left(x-2\right)=60-51=9\)

=> \(x-2=\dfrac{9}{3}=3\)

=> \(x=5\)

chúc em học tốt!

60 - 3 . (x - 2) = 51

       3 . (x - 2) = 60 - 51

       3 . (x - 2) = 9

             x - 2  = 9 : 3

             x - 2  = 3

                     => x = 1

             Vậy x = 1

Đáp án cần chọn là: A

x=5

đúng nha kagome

60-3(X-2)=51

=>3(X-2)=60-51

=>3(X-2)=9

=>X-2=9:3

=>X-2=3

=>X=3+2

=>X=5

<=> 3.(x - 2) = 60 - 51 = 9

x - 2 = 9 : 3 = 3

x = 3 + 2

x = 5

nha bn

60-3 (x-2) =51

    3(x-2)=60-51

    3(x-2)=9

    (x-2)=9:3

    x-2=3

    x=3+2

    x=5

60-3.(x-2)=51

     3.(x-2)=60-51

     3.(x-2)=9

        x-2  =9:3

        x-2  =3

        x     =3+2

        x     =5

60 - 3 ( x - 2 ) = 51

=>3 ( x - 2) = 60 - 51

=> 3 ( x - 2 ) = 9

=> x - 2 = 9 : 3

=> x - 2 = 3

=> x = 3 + 2

=> x = 5.

Vậy x = 5.

60 - 3 (x - 2 ) = 51

3(x-2) = 60-51

3(x-2) = 9

x-2 = 9:3

x-2 = 3

x    = 3+2

Vậy x=5 

60-3+.(x-2)=51

3+.(x-2)=60-51

3+.(x-2)=9

đề sai

3 x < x - 2>=60 - 51

3x <x -2>=9

       x - 2 = 9 : 3

      x -2    =  3

          x     = 3 + 2 

          x     = 5

Vậy x = 5
