Question

Giải phương trình:

\(\frac{7}{6}-\frac{5}{2}=\frac{13}{9}+\frac{7}{4}x\)

Answer 1

<=> \(\frac{7}{6}-\frac{13}{9}=\frac{5}{2}x+\frac{7}{4}x\)

<=>\(-\frac{5}{18}=x.\left(\frac{5}{2}+\frac{7}{4}\right)\)

<=>\(-\frac{5}{18}=\frac{17}{4}.x\)

=> \(x=-\frac{5}{18}:\frac{17}{4}\)

\(x=-\frac{10}{153}\)

Answer 2

\(\frac{7}{6}-\frac{5}{2}x\)

nhầm!
