Question

Giá trị x thoả mãn

\(\frac{-\left(-x\right)}{5}-\frac{2}{10}=\frac{1}{-5}-\frac{7}{50}\)

Answer 1

\(-\frac{\left(-x\right)}{5}-\frac{2}{10}=\frac{1}{-5}-\frac{7}{50}\)

\(\Rightarrow\frac{x}{5}-\frac{2}{10}=-\frac{17}{50}\)

\(\Rightarrow\frac{x}{5}=-\frac{17}{50}+\frac{2}{10}\)

\(\Rightarrow\frac{x}{5}=-\frac{7}{50}\)

\(\Rightarrow x\in\theta\)
