Question

`2/13 x+1/4 = 95/26 x-1/3`

Answer 1

=>2/13x-95/26x=-1/3-1/4

=>-91/26x=-7/12

=>-7/2x=-7/12

hay x=1/6

Answer 2

`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.`

Answer 3

`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`

Answer 4

\(\Leftrightarrow\dfrac{2}{13}x-\dfrac{95}{26}x=-\dfrac{1}{3}-\dfrac{1}{4}\\ \Leftrightarrow-\dfrac{7}{2}x=-\dfrac{7}{12}\\ \Leftrightarrow x=-\dfrac{7}{12}:-\dfrac{7}{2}=\dfrac{1}{6}\)
