Question

4.12-3.(x-3)=33

Answer 1

4 . 12 - 3 . ( x - 3 ) = 33

48 - 3 . ( x -3 ) = 33

3 . ( x -3 ) =  48 - 33

3 . ( x - 3 ) = 15

x -3 = 15 : 3

x - 3 = 5 

x       = 5 + 3 

x        = 8

vậy x = 8

Answer 2

4.12 - 3(x - 3) = 33

=> 48 - 3x + 9 = 33

=> 57 - 3x = 33

=> 3x = 24

=> x = 8

Answer 3

4.12-3.(x-3)=33

   48-3.(x-3)=33

       3.(x-3)=48-33

       3.(x-3)=15

            x-3=15:3

            x-3=5

               x=5+3

               x=8

         vậy x=8
