Answer 1

\(\frac{7}{4}-y\)x \(\frac{5}{6}=\frac{1}{2}+\frac{1}{3}\)

\(\frac{7}{4}-y\)x \(\frac{5}{6}=\frac{5}{6}\)

          \(y\) x \(\frac{5}{6}=\frac{7}{4}-\frac{5}{6}\)

          \(y\) x \(\frac{5}{6}=\frac{11}{12}\)

           y              == \(\frac{11}{12}:\frac{5}{6}\) 

           y              == \(\frac{11}{10}\)

Answer 2

Ta có \(\frac{7}{4}-\frac{5}{6}y=\frac{5}{6}\)

\(\frac{7}{4}=\frac{5}{6}y+\frac{5}{6}\)

\(\frac{7}{4}=\frac{5}{6}\left(y+1\right)\)

\(\frac{7}{4}:\frac{5}{6}=y+1\)

\(\frac{7}{4}\cdot\frac{6}{5}=\frac{21}{10}=y+1\)

\(y=\frac{21}{10}-1=\frac{11}{10}\)

Answer 3

\(\frac{7}{4}\)- y x \(\frac{5}{6}\)=\(\frac{5}{6}\)

y x \(\frac{5}{6}\)=\(\frac{5}{6}\)+ \(\frac{7}{4}\)

y x \(\frac{5}{6}\)=\(\frac{31}{12}\)

y=\(\frac{31}{12}\):\(\frac{5}{6}\)

y=\(\frac{31}{10}\)

Answer 4

\(\frac{7}{4}-y\cdot\frac{5}{6}=\frac{5}{6}\)

\(\frac{7}{4}-y=\frac{5}{6}:\frac{5}{6}\)

\(\frac{7}{4}-y=1\)

\(y=\frac{7}{4}-1\)

\(y=\frac{3}{4}\)

Answer 5

kết pủa là \(\frac{11}{10}\)

Answer 6

7\(yx\frac{5}{6}=\frac{7}{4}-\frac{5}{6}\)
