Question

Số nguyên x thỏa mãn x-(-25-7-2x)=6+x là x= 

Answer 1

x - (-25 - 7 - 2x) = 6 + x

x - (-32 - 2x ) = 6 + x

3x + 32 = 6 + x

x - 3x = 32 - 6

-2x = 26

x = -13 

 

Answer 2

x-(-25-7-2x)=6+x

=>x+25+7+2x=6+x

=>3x+32=6+x

=>2x=-26

=>x=-13

Answer 3

    x-(-25-7-2x)=6-x

=>x+25+7+2x=6-x

    x+2x+x       =-25-7+6

        4x           =  -26

          x           =-6,5

        Vậy...................

                                     Nhớ tik mk nha!
