Question

\(\dfrac{x-2}{3}=\dfrac{12}{6}\)  giúp em ạ

Answer 1

`[x-2]/3=12/6`

`[x-2]/3=6/3`

`x-2=6`

`x=6+2=8`

Answer 2

\(\Rightarrow6\left(x-2\right)=3\cdot12\\ \Rightarrow6\left(x-2\right)=36\\ \Leftrightarrow x-2=6\\ \Leftrightarrow x=8\)

Answer 3

\(\dfrac{x-2}{3}=\dfrac{12}{6}\)

\(\Leftrightarrow\dfrac{x-2}{3}=2\)

\(\Rightarrow x-2=6\)

\(\Leftrightarrow x=8\)

Vậy phương trình có nghiệm duy nhất \(x=8\)
