\(x-\dfrac{2}{5}=-\dfrac{1}{5}\)
\(x=\left(-\dfrac{1}{5}\right)+\dfrac{2}{5}\)
\(x=\dfrac{1}{5}\)
\(x=-\dfrac{1}{5}+\dfrac{2}{5}\)
\(x=\dfrac{1}{5}\)
x - 2/5 = - 1/5
x = -1/5 + 2/5
x = 1/5
\(x-\dfrac{2}{5}=-\dfrac{1}{5}\)
\(x=\left(-\dfrac{1}{5}\right)+\dfrac{2}{5}\)
\(x=\dfrac{1}{5}\)
\(x=-\dfrac{1}{5}+\dfrac{2}{5}\)
\(x=\dfrac{1}{5}\)
x - 2/5 = - 1/5
x = -1/5 + 2/5
x = 1/5
