\(y-\dfrac{2}{7}=\dfrac{8}{9}\)
<=> \(y=\dfrac{8}{9}+\dfrac{2}{7}\)
<=> \(y=\dfrac{74}{63}\)
\(y-\dfrac{2}{7}=\dfrac{8}{9}\Rightarrow y=\dfrac{8}{9}+\dfrac{2}{7}\)
\(\Rightarrow y=\dfrac{56+18}{63}=\dfrac{74}{63}\)
\(y-\dfrac{2}{7}=\dfrac{8}{9}\)
\(y=\dfrac{8}{9}+\dfrac{2}{7}\)
\(y=\dfrac{56}{63}+\dfrac{18}{63}\)
\(y=\dfrac{74}{63}\)
