\(y+1\frac{21}{22}=2\frac{43}{44}\Rightarrow y+\frac{43}{22}=\frac{131}{44}\Rightarrow y=\frac{131}{44}-\frac{86}{44}\Rightarrow y=\frac{45}{44}\)
\(y+1\frac{21}{22}=2\frac{43}{44}\)
\(y+\frac{43}{22}=\frac{131}{44}\)
y \(=\)\(\frac{131}{44}-\frac{43}{22}=\frac{45}{44}\)
Bài làm :
\(y+1\frac{21}{22}=2\frac{43}{44}\Leftrightarrow y+\frac{43}{22}=\frac{131}{44}\Leftrightarrow y=\frac{45}{44}\)
\(y+1\frac{21}{22}=2\frac{43}{44}.\)
\(y=2\frac{43}{44}-1\frac{21}{22}.\)
\(y=\frac{45}{44}.\)
\(y+1\frac{21}{22}\)\(=2\frac{43}{44}\)
\(y+\frac{43}{22}\)\(=\frac{131}{44}\)
\(y=\frac{131}{44}\)\(-\frac{43}{22}\)
\(\Rightarrow\)\(y=\frac{45}{44}\)
