Question

tìm x

g) 45-5.(x+2)=10

Answer 1

45 - 5(x+2)=10

-5(x+2)=10-45

-5(x+2)=-35

x+2=-35:(-5)

x+2=7

x=7-2

x=5

Answer 2

x=5 nha!

Answer 3

\(45-5.\left(x+2\right)=10\)

\(5.\left(x+2\right)=45-10\)

\(5.\left(x+2\right)=35\)

\(x+2=35\div5\)

\(x+2=7\)

\(x=7-2\)

\(x=5\)

Vậy .....

Answer 4

\(45-5\times\left(x+2\right)=10\)

\(5\times\left(x+2\right)=45-10\)

\(5\times\left(x+2\right)=35\)

\(x+2=35:5\)

\(x+2=7\)

\(x=7-2\)

\(x=5\)

Answer 5

45-5.(x+2)=10

5.(x+2)     =45-10

5.(x+2)     =35

x+2          =35:5

x+2          =7

x              =7-2

x              =5

Vậy x bằng 5

Answer 6

45 - 5.(x + 2) = 10

       5.(x + 2) = 45 - 10

       5.(x + 2) = 35

          x + 2 = 35 : 5

          x + 2 = 7

               x = 7 - 2

              x = 5

Answer 7

45-5.(x+2)=10

40.(x+2)=40-10=30

            =30-2

            =28

Answer 8

45-5(x+2)=10

5(x+2)=45-10

5(x+2)=35

x+2=35:5

x+2=7

x=7-2

x=5

Answer 9

\(45-5.\left(x+2\right)=10\)

\(5.\left(x+2\right)=45-10\)

\(5.\left(x+2\right)=35\)

\(x+2=35\div5\)

\(x+2=7\)

\(x=7-2\)

\(x=5\)

Answer 10

45 - 5.(x + 2) = 10

       5.(x + 2) = 45 - 10

       5.(x + 2) = 35

            x + 2 = 35 : 5

            x + 2 = 7

                  x = 7 - 2

                  x = 5

Answer 11

45 - 5 . (x + 2) = 10

    45 - 10        = 5 . (x + 2)

         35           = 5 . (x + 2)

           35 : 7     = x + 2

               5        = x + 2

               x        = 5 - 2

                 x       = 3

       

Answer 12

45 - 5 × ( x + 2 ) = 10

5 ( x + 2 ) = 45 - 10

5 ( x + 2 ) = 35

x + 2 = 35 ÷ 5

x + 2 = 7

x = 7 - 2

x = 5

Answer 13

45 - 5.(x + 2) = 10

       5.(x + 2) = 45 - 10

       5.(x + 2) = 35

            x + 2 = 35 : 5

            x + 2 = 7

                  x = 7 - 2

                  x = 5

Answer 14

45 - 5.(x + 2) = 10

       5.(x + 2) = 45 - 10

       5.(x + 2) = 35

            x + 2 = 35 : 5

            x + 2 = 7

                  x = 7 - 2

                  x = 5

Answer 15

45 - 5.(x + 2) = 10

       5.(x + 2) = 45 - 10

       5.(x + 2) = 35

            x + 2 = 35 : 5

            x + 2 = 7

                  x = 7 - 2

                  x = 5
