$\frac{2x}{5} + 1 = \frac{1}{15}$

---------------------------------------------------------
Take away 1 from both sides
---------------------------------------------------------
$\frac{2x}{5} = \frac{1}{15} - 1$

---------------------------------------------------------
Evaluate the value on the right
---------------------------------------------------------
$\frac{2x}{5} = - \frac{14}{15}$

----------------------------------------------------------
Multiply by 15 on both side
---------------------------------------------------------
$\frac{2x}{5} \times 15 = - \frac{14}{15} \times 15$

---------------------------------------------------------
Evaluate
---------------------------------------------------------
$6x = -14$

---------------------------------------------------------
Divide by 6 on both sides
---------------------------------------------------------
$x = - \frac{14}{6}$

---------------------------------------------------------
Simplify
---------------------------------------------------------
$x = - \frac{7}{3}$

$Answer \: x = - \frac{14}{6} \ or - \frac{7}{3}$
