`(5x-2)/6=(x+7)/3`
`<=>3(5x-2)=6(x+7)`
`<=>15x-6=6x+42`
`<=>9x=48`
`<=>x=16/3`
Vậy `S={16/3}`
Ta có
\(5x-\dfrac{2}{6}=x+\dfrac{7}{3}\\ 4x=\dfrac{8}{3}\\ x=\dfrac{2}{3}\)
\(5x-\dfrac{2}{6}=x+\dfrac{7}{3}\)
\(\Leftrightarrow\dfrac{30x}{6}-\dfrac{2}{6}=\dfrac{6x}{6}+\dfrac{14}{6}\)
\(\Leftrightarrow30x-2=6x+14\)
\(\Leftrightarrow24x=16\)
\(\Leftrightarrow x=\dfrac{2}{3}\)
Ta có: \(\dfrac{5x-2}{6}=\dfrac{x+7}{3}\\ \dfrac{5x-2}{2}=x+7\\ 5x-2=2x +14\\ 3x=16\\ x=\dfrac{16}{3}\)
`(5x-2)/6=(x+7)/3`
`<=>(5x-2)/6=(2x+14)/6`
`<=>5x-2=2x+14`
`<=>3x=16`
`<=>x=16/3`
Vậy `S={16/3}`
