125-5.(3x-1)=25

Answer 1

125 - 5.(3x - 1) = 25

          5.(3x - 1) = 125 - 25

          5.(3x - 1) = 100

                3x - 1 = 100 : 5

                3x - 1 = 20

                      3x = 20 + 1

                      3x = 21

                        x = 21 : 3

                        x = 7

Vậy x = 7

Answer 2

Dễ vậy cx hỏi

Answer 3

Tốn diện tích

Answer 4

125-5.(3x-1)=25

      -5.(3x-1)=-100

            3x+1=20

            3x    =19

              x    =19/3

Answer 5

\(5.\left(3x-1\right)=125-25\)

\(5.\left(3x-1\right)=100\)

\(3x-1=100:5\)

\(3x-1=20\)

\(3x=20+1\)

\(3x=21\)

\(x=21:3\)

\(x=7\)

Vậy \(x\)=7

Answer 6

125-5.(3x-1)=25

            3x-1 = 20

              x    = 7

Answer 7

\(125-5.\left(3x-1\right)=25\)

\(\Rightarrow5.\left(3x-1\right)=100\)

\(\Rightarrow3x-1=20\)

\(\Rightarrow3x=21\)

\(\Rightarrow x=7\)

Vậy x = 7
