\(\Rightarrow y\times\dfrac{1}{2}=\dfrac{5}{4}-\dfrac{2}{3}=\dfrac{7}{12}\\ \Rightarrow y=\dfrac{7}{12}:\dfrac{1}{2}=\dfrac{7}{12}\times2=\dfrac{7}{6}\)
\(\dfrac{2}{3}+y\times\dfrac{1}{2}=\dfrac{5}{4}\)
\(\Rightarrow y\times\dfrac{1}{2}=\dfrac{5}{4}-\dfrac{2}{3}\)
\(\Rightarrow y\times\dfrac{1}{2}=\dfrac{7}{12}\)
\(\Rightarrow y=\dfrac{7}{12}:\dfrac{1}{2}\)
\(\Rightarrow y=\dfrac{7}{6}\)
