Question

tìm x biết: \(2009-\left(4\frac{5}{9}+x-7\frac{7}{8}\right):15\frac{3}{2}=2008\)

Answer 1

\(2009-\left(4\frac{5}{9}+x-7\frac{7}{8}\right):15\frac{3}{2}=2008\)

\(\Leftrightarrow2009-\left(\frac{41}{9}+x-\frac{63}{8}\right):\frac{33}{2}=2008\)

\(\Leftrightarrow2009-\left(x-\frac{239}{72}\right):\frac{33}{2}=2008\)

\(\Leftrightarrow2009-\frac{2x}{33}+\frac{239}{1188}=2008\)

\(\Leftrightarrow\frac{-2x}{33}=\frac{-1427}{1188}\)

\(\Leftrightarrow-2376x=-47091\)

\(\Leftrightarrow x=\frac{1427}{72}\)
