Question

70-5.(x-3)=5.9

giup mik nha

Answer 1

70-5.(x-3)=5.9

70-5.(x-3)=45

5.(x-3)=70-45

5.(x-3)=25

x-3=25:5

x-3=5

x=5+3=8

Vậy x=8

Answer 2

70-5(x-3)=5.9

=>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

Answer 3

70 - 5 ( x - 3 ) = 5 . 9

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

Answer 4

=>70-5x-15=45

=>55-5x=45

=>5x=55-45

=>5x=10

=>x=10:2

=>x=5

Answer 5

70 - 5 .( x - 3 ) = 5 .9

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

Answer 6

Tra loi : 70-5.(x-3)=5.9 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 gia tri can tim la x=8

Answer 7

70 -5.(x-3)=5.9

70 - 5 .(x-3) =45

5.(x-3)=70-45

5.(x-3)=35

x-3=35:5

x-3 =7

x=7+3

x=10

vậy x=10

Answer 8

Làm

     70 - 5 ( x - 3 ) = 5 . 9

=> 70 - 5 ( x - 3 ) = 45

=>        5 ( x - 3 ) = 70 - 45

=>        5 ( x - 3 ) = 25

=>              x - 3  = 25 : 5

=>              x - 3  = 5

=>              x       = 8

Vậy x = 8

Answer 9

\(70-5.\left(x-3\right)=5.9\)

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

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

            \(5.\left(x-3\right)=25\)

                \(\left(x-3\right)=25:5\)

                      \(x-3=5\)

                           \(x=5+3\)

                           \(x=8\)

               Vậy \(x=8\)

Answer 10

70-5(x+3)=5.9

70-5(x+3)=45

5(x-3)=70-45

5(x-3)=25

x-3=25:5

x=5+3

x=8

Vậy x=8
