\(\left(\dfrac{9}{2}-2x\right)\cdot1\dfrac{4}{7}=\dfrac{11}{14}\\ \\\\ \Rightarrow\left(\dfrac{9}{2}-2x\right)\cdot\dfrac{11}{7}=\dfrac{11}{14}\\ \\\\ \Rightarrow\dfrac{9}{2}-2x=\dfrac{11}{14}:\dfrac{11}{7}=\dfrac{11}{14}\cdot\dfrac{7}{11}=\dfrac{1}{2}\\ \\ \\ \Rightarrow2x=\dfrac{9}{2}-\dfrac{1}{2}=\dfrac{8}{2}=4\\ \\ \\ \Rightarrow x=4:2=2\)
(\(\dfrac{9}{2}\) - 2\(x\)) \(\times\) 1\(\dfrac{4}{7}\) = \(\dfrac{11}{14}\)
( \(\dfrac{9}{2}\) - 2\(x\)) \(\times\) \(\dfrac{11}{7}\) = \(\dfrac{11}{14}\)
\(\dfrac{9}{2}\) - 2\(x\) = \(\dfrac{11}{14}\) : \(\dfrac{11}{7}\)
\(\dfrac{9}{2}\) - 2\(x\) = \(\dfrac{1}{2}\)
2\(x\) = \(\dfrac{9}{2}\) - \(\dfrac{1}{2}\)
2\(x\) = 4
\(x\) = 4 : 2
\(x\) = 2
