\(\frac{5}{8}-\frac{3}{8}.x=\left(-\frac{1}{2}\right)^4+\frac{5}{6}\)
\(\Leftrightarrow\frac{5}{8}-\frac{3}{8}.x=\frac{1}{16}+\frac{5}{6}\)
\(\Leftrightarrow\frac{3}{8}.x=\frac{5}{8}-\left(\frac{1}{16}+\frac{5}{6}\right)\)
\(\Leftrightarrow\frac{3}{8}.x=\frac{5}{8}-\frac{5}{96}\)
\(\Leftrightarrow\frac{3}{8}.x=\frac{55}{96}\)
\(\Leftrightarrow x=\frac{55}{96}:\frac{3}{8}\)
\(\Leftrightarrow x=\frac{55}{36}\)
Vậy : \(x=\frac{55}{36}\)
