Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 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

Answer 7

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

Answer 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

k nha ^_-

Answer 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 10

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 11

vậy x=8

mình chăc chắn đó

bn ạ mình ko có tính nhầm

đâu mong bn

Answer 12

5.(x-3)= 70-45

5.(x-3)=25

x-3= 25:5

x-3= 5

x=5+3

x=8
