`4(x – 1/3) – 2(x + 1/2) = x – 3/4` `⇔4x – 4/3 – 2x – 1 = x – 3/4` `⇔4x – 2x – x = -3/4 + 1 + 4/3` `⇔x = 19/12` $\text{Vậy x = $\dfrac{19}{12}$}$ Bình luận
4(x-$\frac{1}{3}$)-2(x+ $\frac{1}{2}$)=x- $\frac{3}{ 4}$ ⇔ 4x-$\frac{4}{3}$-2x-1-x-$\frac{3}{4}$=0 ⇔x-$\frac{19}{12}$ =0 ⇔x=$\frac{19}{12}$ Vậy S={$\frac{19}{12}$} Bình luận
`4(x – 1/3) – 2(x + 1/2) = x – 3/4`
`⇔4x – 4/3 – 2x – 1 = x – 3/4`
`⇔4x – 2x – x = -3/4 + 1 + 4/3`
`⇔x = 19/12`
$\text{Vậy x = $\dfrac{19}{12}$}$
4(x-$\frac{1}{3}$)-2(x+ $\frac{1}{2}$)=x- $\frac{3}{ 4}$
⇔ 4x-$\frac{4}{3}$-2x-1-x-$\frac{3}{4}$=0
⇔x-$\frac{19}{12}$ =0
⇔x=$\frac{19}{12}$
Vậy S={$\frac{19}{12}$}
