Question

6(x-2)+(-2)=20-4x

Answer 1

\(6.\left(x-2\right)+\left(-2\right)=20-4x\)

\(\Leftrightarrow\)\(6x-12-2=20-4x\)

\(\Leftrightarrow\)\(6x-4x=20+12+2\)

\(\Leftrightarrow\)\(2x=34\)

\(\Leftrightarrow\)\(x=\frac{34}{2}=17\)

Vậy \(x=17\)

Answer 2

6(x-2)+(-2)=20-4x

6x - 6.2 - 2 = 20 - 4x

6x - 12 - 2 = 20 - 4x

6x - 14 = 20 - 4x

6x + 4x = 20 + 14

10x = 34

x = 34 : 10

x = 3,4

Answer 3

6(x-2)+(-2)=20-4x

=> 6x-12-2=20-4x

=>.       6x+4x=20+12+2

=>.      10x=34

=>           x=34:10

=>.          x=34/10

         Vậy x= 34/10
