\(\frac{4}{5}-\frac{3}{2}.x=\frac{7}{15}\)
\(\Leftrightarrow-\frac{3}{2}x=\frac{7}{15}-\frac{4}{5}=-\frac{1}{3}\)
\(\Leftrightarrow x=-\frac{1}{3}:\left(-\frac{3}{2}\right)=\frac{2}{9}\)
vậy x=\(\frac{2}{9}\)
\(\frac{4}{5}-\frac{3}{2}.x=\frac{7}{15}\)
\(\frac{3}{2}x=\frac{4}{5}-\frac{7}{15}\)
\(\frac{3}{2}x=\frac{1}{3}\)
\(x=\frac{1}{3}:\frac{3}{2}\)
\(x=\frac{2}{9}\)
Ta có: \(\frac{4}{5}-\frac{3}{2}.x=\frac{7}{15}\)
\(\Rightarrow\frac{3}{2}.x=\frac{4}{5}-\frac{7}{15}\)
\(\Rightarrow\frac{2}{3}.x=\frac{12}{15}-\frac{7}{15}\)
\(\Rightarrow\frac{2}{3}.x=\frac{1}{3}\)
\(\Rightarrow x=\frac{1}{3}:\frac{2}{3}\)
\(\Rightarrow x=\frac{1}{3}.\frac{3}{2}\)
\(\Rightarrow x=\frac{1}{2}\)
Vậy \(x=\frac{1}{2}\)
