Answer

$x = 1\frac{3}{7}$

Work Step by Step

$\frac{1}{5}x = \frac{2}{7}$ We need to isolate the variable $x$ by multiplying through by the reciprocal of the coefficient of $x$ as shown below: $\frac{1}{5}x \times \frac{5}{1} = \frac{2}{7} \times \frac{5}{1}$ Simplify to get: $x = \frac{10}{7}$ Leaving the answer in the simplest form, we have: $x = 1\frac{3}{7}$
