\(70-5\left(x-3\right)=45\)

\(\Rightarrow5\left(x-3\right)=30\)

\(\Rightarrow x-3=6\Rightarrow x=9\)

\(70-5\left(x-3\right)=45\)

\(\Leftrightarrow5\left(x-3\right)=25\)

\(\Leftrightarrow x-3=5\)

hay x=8

70-5(x-3)=-45

=>5(x-3)=70+45=115

=>x-3=23

=>x=23+3=26

70 - 5(x - 3) = -45

=> 5(x - 3) = 70 - (-45)

=> 5(x - 3) = 115

=> x - 3 = 23

=> x =  26

70-5(x-3)=45

     5(x-3)=70-45=25

         x-3= 25:5=5

            x=5+3

            x=8

70-5(x-3)=45

     5(x-3)=70-45

     5(x-3)=25

       (x-3)=25:5

        x-3=5

         x=5+3

         x=8

70-5(x-3)=45

5(x-3)=70-45

5(x-3)=25

x-3=25:5

x-3=5

x=5+3

x=8

Vay x=8

Tìm x

70-5.(x-3)=45

       5(x-3) =70-45

        5(x-3) =    25

            x-3 = 25:5

              x-3 = 5

                  x=5+3

                    x=8

70 - 5.(x - 3) = 45

=> 5.(x - 3) = 35

=> x - 3 = 7

=> x = 10

70 - 5 ( x - 3 ) = 45

5 ( x - 3 ) = 70 - 45 = 25

x - 3 = 25 : 5 = 5

    x = 5 + 3

    x = 8

70 – 5.(x – 3) = 45

5.(x -3) = 70 - 45

5.(x – 3) = 25

x – 3 = 25 : 5

x – 3 = 5

x = 5 + 3

x = 8

Vậy x = 8

70-5.(x-3)=45

=> 5.(x-3)=70-45

=> 5.(x-3)=25

=> x-3=25:5

=> x-3=5

=> x=5+3

Vậy x=8.

70 - 5 . ( x - 3 ) = 45

       5 . ( x - 3 ) = 70 - 45

        5 . ( x - 3 ) = 15

               x - 3   = 15 : 5

               x - 3   = 3

                x        = 3 + 3

                x         = 6

70-5.(x-3)=45

5.(x-3)=70-45

5.(x-3)=25

x-3=25:5

x-3=5

x=5+3

x=8
