\(\frac{1}{2}.x+\frac{3}{5}.x=-\frac{33}{25}\)
\(\Leftrightarrow x.\left(\frac{1}{2}+\frac{3}{5}\right)=-\frac{33}{25}\)
\(\Leftrightarrow x.\frac{11}{10}=-\frac{33}{25}\)
\(\Leftrightarrow x=-\frac{33}{25}:\frac{11}{10}\)
\(\Leftrightarrow x=-\frac{6}{5}\)
Vậy \(x=\frac{6}{5}\)
\(\frac{1}{2}.x+\frac{3}{5}.x=-\frac{33}{25}\)
\(x.\left(\frac{1}{2}+\frac{3}{5}\right)=-\frac{33}{25}\)
\(x.\left(\frac{5}{10}+\frac{6}{10}\right)=-\frac{33}{25}\)
\(x.\frac{11}{10}=-\frac{33}{25}\)
\(x=-\frac{33}{25}:\frac{11}{10}\)
\(x=-\frac{33}{25}.\frac{10}{11}\)
\(x=-\frac{6}{5}\)
Vậy \(x=-\frac{6}{5}\)
Chúc bạn học tốt !!!
\(\frac{1}{2}\).x+\(\frac{3}{5}\).x=\(\frac{33}{25}\)
x.\((\frac{1}{2}\)+\(\frac{3}{5})\)=\(\frac{33}{25}\)
x.\((\frac{5}{10}+\frac{6}{10})=\frac{33}{25}\)
\(x.\frac{11}{10}=\frac{33}{25}\)
\(x=\frac{33}{25}:\frac{11}{10}\)
x=\(\frac{6}{5}\)
