Question

6(x-2)=5x-8

Answer 1

`6(x-2)=5x-8`

`<=>6x-12=5x-8`

`<=>6x-5x=-8+12`

`<=>x=4`

Answer 2

\(6\left(x-2\right)=5x-8\)
\(\Leftrightarrow6x-12=5x-8\)
\(\Rightarrow6x-5x=-8+12\)
\(\Rightarrow x=4\)

Answer 3

    \(6\left(x-2\right)=5x-8\)

⇔ \(6x-5x=12-8\)

⇔ \(x=4\)

Vậy \(S=\left\{4\right\}\)

Answer 4

\(6\left(x-2\right)=5x-8\)

\(\Leftrightarrow6x-12=5x-8\)

\(\Leftrightarrow6x-5x=12-8\)

\(\Leftrightarrow x=4\)

\(\text{Vậy phương trình có tập nghiệm là }S=\left\{4\right\}\)
