\(|5x - 2| = 4\)
\(5x - 2 = 4\)
\(\dfrac{5x}{5} - \dfrac{2}{5} = \dfrac{4}{5}\)
\(x - \dfrac{2}{5} + \dfrac{2}{5} = \dfrac{4}{5} + \dfrac{2}{5}\)
\(x_{1} = \dfrac{6}{5}\)
\(and\)
\(|5x - 2| = -4\)
\(5x - 2 = -4\)
\(\dfrac{5x}{5} - \dfrac{2}{5} = -\dfrac{4}{5}\)
\(x - \dfrac{2}{5} + \dfrac{2}{5} = -\dfrac{4}{5} + \dfrac{2}{5}\)
\(x_{2} = -\dfrac{2}{5}\)
\(\{-\dfrac{2}{5}, \dfrac{6}{5} \}\)
