Answer 1

(x+2x+3x)-(8+15+27)=4x+68

     6x       -      50       =4x+68

     6x- 4x                   =68+50

         2x                      =118

            59    =x

Answer 2

\(x-8+2x-15+3x-27=4x+68\)

\(\Leftrightarrow6x-50=4x+68\)

\(\Leftrightarrow6x-4x=68+50\)

\(\Leftrightarrow2x=118\)

\(\Leftrightarrow x=59\)

Answer 3

x-8+2x-15+3x-27=4x+68

(x+2x+3x)-8-15-27=4x+68

6x-(8+15+27)=4x+68

6x-50=4x+68

6x=4x+68+50

6x-4x=68+50

2x=118

x=118:2

x=59

Vậy x=59.k cho mk nha
