Answer 1

[Vy Thị Hoàng Lan ( Toán Học )]

\(\frac{4}{11}.y-\frac{6}{11}=\frac{2}{5}\Leftrightarrow\frac{4}{11}y=\frac{2}{5}+\frac{6}{11}\)

\(\Leftrightarrow\frac{4}{11}y=\frac{52}{55}\Rightarrow y=\frac{52}{55}:\frac{4}{11}\)

\(\Rightarrow y=\frac{13}{5}\)

Answer 2

[nguyễn tuấn thảo]

\(\frac{4}{11}\times y-\frac{6}{11}=\frac{2}{5}\)

\(\Rightarrow\frac{4}{11}\times y=\frac{2}{6}+\frac{6}{11}\)

\(\Rightarrow\frac{4}{11}\times y=\frac{29}{33}\)

\(\Rightarrow y=\frac{29}{33}:\frac{4}{11}\)

\(\Rightarrow y=\frac{29}{33}\times\frac{11}{4}\)

\(\Rightarrow y=\frac{29}{12}\)
