x - x/2 = 32/15 : -16/5
=> x(1 - 1/2) = -2/3
=> x.1/2 = -2/3
=> x = -4/3
vậy_
\(x-\frac{x}{2}=\frac{32}{15}:-\frac{16}{5}\)
\(x\cdot\left(1-\frac{1}{2}\right)=-\frac{2}{3}\)
\(x\cdot\frac{1}{2}=-\frac{2}{3}\)
\(x=-\frac{2}{3}:\frac{1}{2}\)
\(x=-\frac{4}{3}\)
\(x-\frac{x}{2}=\frac{32}{15}:\frac{-16}{5}\)
\(\Leftrightarrow\)\(x-\frac{x}{2}=\frac{-2}{3}\)
\(\Leftrightarrow\)\(x=\frac{-2}{3}+\frac{x}{2}\)
\(\Leftrightarrow\)\(x=\frac{-4}{6}+\frac{3x}{6}\)
\(\Leftrightarrow\)\(x=\frac{-4+3x}{6}\)
\(\Leftrightarrow\)\(6x=-4+3x\)
\(\Leftrightarrow\)\(2x=-4\)
\(\Leftrightarrow\)\(x=-2\)
Vậy.....
\(x-\frac{x}{2}=\frac{32}{15}:\frac{-16}{5}\)
\(\Leftrightarrow x-\frac{x}{2}=\frac{32}{15}.\frac{-5}{16}\)
\(\Leftrightarrow x-\frac{x}{2}=-\frac{2}{3}\)
\(\Leftrightarrow x=-\frac{2}{3}+\frac{x}{2}\)
\(\Leftrightarrow x=-\frac{4}{6}+\frac{3x}{6}\)
\(\Leftrightarrow x=\frac{-4+3x}{6}\)
\(\Leftrightarrow6x=-4+3x\)
\(\Leftrightarrow6x-3x=-4\)
\(\Leftrightarrow x=-4:3\)
\(\Leftrightarrow x=-\frac{4}{3}\)
