Question

tìm x:

 4x-2(2-x)=56

Answer 1

 4x-2(2-x)=56

=>4x-4+2x=56

=>6x=60

=>x=10

vay x=10

Answer 2

4x - 2(2 - x) = 56

  4x - 4 + 2x = 56

         6x - 4 = 56

               6x = 56 + 4

                6x = 60

                  x = 10

Answer 3

<=>4x-4+2x=56

<=>6x-4      =56

<=>6x         =56+4=60

<=>x           =60:6=10

Vậy x=10
