Question

Giải phương trình: 

\(\frac{3}{4}x-\frac{5}{6}=\frac{7}{8}\)

Answer 1

ta có: \(\frac{3}{4}x-\frac{5}{6}=\frac{7}{8}\)<=> \(\frac{3}{4}x=\frac{41}{24}\)

                                => \(x=\frac{41}{18}\)

Vậy x= \(\frac{41}{18}\)

Answer 2

Ta có: \(\frac{3}{4}x-\frac{5}{6}=\frac{7}{8}\)

\(\Rightarrow\frac{3}{4}x=\frac{7}{8}+\frac{5}{6}\)

\(\Rightarrow\frac{3}{4}x=\frac{21}{24}+\frac{20}{24}\)

\(\Rightarrow\frac{3}{4}x=\frac{41}{24}\)

\(\Rightarrow x=\frac{41}{24}:\frac{3}{4}\)

\(\Rightarrow x=\frac{41}{24}.\frac{4}{3}\)

\(\Rightarrow x=\frac{41}{18}\)

Vậy \(x=\frac{41}{18}\)
