$x+\dfrac{5}{2}.\dfrac{2}{3}=\dfrac{5}{2}$ $x+\dfrac{5}{3}=\dfrac{5}{2}$ $x=\dfrac{5}{2}-\dfrac{5}{3}$ $x=\dfrac{15}{6}-\dfrac{10}{6}$ $→x=\dfrac{5}{6}$ Vậy $x=\dfrac{5}{6}$ Lưu ý: Dấu “.” là nhân Bình luận
`x + 5/2 × 2/3 = 52`
`x + 5/3 =52`
`x=52 – 5/3`
`x= 151/3`
Vậy `x= 151/3`
$x+\dfrac{5}{2}.\dfrac{2}{3}=\dfrac{5}{2}$
$x+\dfrac{5}{3}=\dfrac{5}{2}$
$x=\dfrac{5}{2}-\dfrac{5}{3}$
$x=\dfrac{15}{6}-\dfrac{10}{6}$
$→x=\dfrac{5}{6}$
Vậy $x=\dfrac{5}{6}$
