Question

-45:5(-3-2x)=3

Answer 1

-45:5(-3-2x)=3

5(-3-2x)= -45:3

5(-3-2x)=-15

-3-2x= -15:5

-3-2x= -3

  2x= -3-(-3)

2x= 0

x= 0:2

x= 0

Vậy x= 0

Answer 2

-45:5(-3-2x) = 3

      5(-3-2x) = 3.(-45)

      5(-3-2x) = -135

         -3-2x  = (-135) : 5

        -3-2x   = -27

            2x   = (-27) + (-3)

           2x    = -30

             x    = (-30) : 2

            x    = -15

Answer 3

- 45 : 5 ( - 3 - 2x ) = 3

- 45 : ( - 15 ) - 5 . 2x = 3

3 - 5 . 2x  = 3

5 . 2x = 3 - 3

5 . 2x = 0

2x = 0 : 5

2x = 0

x = 0 : 2 

x = 0

Answer 4

x = 0 nha bn
