\(\dfrac{x}{2}-\dfrac{x}{3}=-2\)
\(\Leftrightarrow\dfrac{3x}{6}-\dfrac{2x}{6}=\dfrac{-12}{6}\)
\(\Rightarrow3x-2x=-12\)
\(\Rightarrow x=-12\)
Vậy x = -12 thì GTBT bằng -2
Ta có:
\(\dfrac{x}{2}-\dfrac{x}{3}=-2\\ \Rightarrow\dfrac{3x}{6}-\dfrac{2x}{6}=-2\\ \Rightarrow\dfrac{x}{6}=-2\\ \Rightarrow x=-2.6\\ \Rightarrow x=-12\)
Vậy \(x=-12\)
