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

Answer 2

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

=> -3-2x = -15 : 5 = -3

=> 2x = -3 - (-3) = 0

=> x = 0 : 2 = 0

Vậy x = 0

Tk mk nha

Answer 3

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

-9.(-3 - 2x) =3

-3 - 2x = -9 . 3

 -3-2x = - 27

 2x = -27 -3

 2x = -24

x = -24: 2

x= -12
