Question

Giúp vs ạ

Answer 1

\(\dfrac{9x-6-7x+9}{6}-x+\dfrac{x-1}{3}\le0\)

\(\Leftrightarrow\dfrac{2x+3-6x+2x-2}{6}\le0\Leftrightarrow\dfrac{-2x+1}{6}\le0\)

\(\Rightarrow\left\{{}\begin{matrix}-2x+1< 0\\-2x+1\ne0\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}x>\dfrac{1}{2}\\x\ne\dfrac{1}{2}\end{matrix}\right.\)
