\(\dfrac{17}{6}-\left(x-\dfrac{7}{6}\right)=\dfrac{7}{4}\)
\(\Leftrightarrow\dfrac{17}{6}-x-\dfrac{7}{6}=\dfrac{7}{4}\)
\(\Leftrightarrow\left(\dfrac{17}{6}-\dfrac{7}{6}\right)-x=\dfrac{7}{4}\)
\(\Leftrightarrow\dfrac{5}{3}-x=\dfrac{7}{4}\)
\(\Leftrightarrow x=-\dfrac{1}{12}\)
Vậy ...
Chị Nguyễn Thanh Hằng check giúp em nhé!
Giải:
\(\dfrac{17}{6}-\left(x-\dfrac{7}{6}\right)=\dfrac{7}{4}\)
\(\Leftrightarrow\dfrac{17}{6}-x+\dfrac{7}{6}=\dfrac{7}{4}\)
\(\Leftrightarrow\dfrac{24}{6}-x=\dfrac{7}{4}\)
\(\Leftrightarrow4-x=\dfrac{7}{4}\)
\(\Leftrightarrow x=4-\dfrac{7}{4}\)
\(\Leftrightarrow x=\dfrac{9}{4}\)
Vậy ...
Nó cố tình làm nhục Hằng kìa :) T khinh
