Question

tim x:

x+1000-200=2000

70-5.(x-3)=45

Answer 1

x+1000-200=2000

x+1000=2200

x=2200-1000

x=1200

70-5.(x-3)=45

5.(x-3)=70-45

5.(x-3)=25

x-3=5

x=8

Answer 2

x+1 000 - 200 = 2 000 

x + 1000=2200

x=1200

vậy x=1200.

70-5.(x-3)=45

5.(x-3)=25

x-3=5

x=8.

vậy x=8.

Answer 3

x + 1000 - 200 = 2000

x + 1000 = 2000 + 200

x + 1000 = 2200

          x = 2200 - 1000

          x = 1200

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

1)x+1000-200=2000

x+1000      =2000+200

x+1000      =2200

x               =2200-1000

x               =1200

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 5

x + 1000 - 200 = 2000

x + 1000 = 2000 + 200

x + 1000 = 2200

x = 2200 - 1000

x = 1200 

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

x = 1200

x = 8
