=>2/13x-95/26x=-1/3-1/4
=>-91/26x=-7/12
=>-7/2x=-7/12
hay x=1/6
`2/13 x+1/4 = 95/26 x-1/3`
`<=>95/26x-2/13x=1/4+1/3`
`<=>91/26x=7/12`
`<=>7/2x=7/2`
`x=7/12:7/2`
`x=7/12xx2/7`
`x=1/6`
Vậy pt có nghiệm duy nhất `x=1/6.`
`2/13x+1/4=95/26x-1/3`
`<=>2/13x-95/26x=-1/3-1/4`
`<=>(2/13-95/26)x=-7/12`
`<=>-7/2x=-7/12`
`<=>x=1/6`
\(\Leftrightarrow\dfrac{2}{13}x-\dfrac{95}{26}x=-\dfrac{1}{3}-\dfrac{1}{4}\\ \Leftrightarrow-\dfrac{7}{2}x=-\dfrac{7}{12}\\ \Leftrightarrow x=-\dfrac{7}{12}:-\dfrac{7}{2}=\dfrac{1}{6}\)
