$x = - \frac{1}{6}$ $x=-1/6$

First, we take the LCM, which is $5$ $5$ . We multiply all the terms by $5$ $5$ . In this way, the denominator will be eliminated. So it will be

$10 x + 1 = 4 x$ $10x+1=4x$

We will isolate the variables on one side and it will be

$10 x - 4 x = - 1$ $10x-4x=-1$

By subtracting, it would become

$6 x = - 1$ $6x=-1$

Divide both sides by $6$ $6$

$x = - \frac{1}{6}$ $x=-1/6$
