#x=-1/6#

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

#10x+1=4x#

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

#10x-4x=-1#

By subtracting, it would become

#6x=-1#

Divide both sides by #6#

#x=-1/6#
