Solve the equation for x

To solve this for x, we need to get the x-term alone.

There is a 3a attached to the x-term by multiplication.

Therefore, we will need to divide both sides by 3a:

   (3ax) / (3a)  =  (1/5) / (3a)

                  x   =  1/(15a)

Note:  (1/5) / (3a)  =  (1/5) x (1/3a)   =   1/(15a)  

   To get the numerator, multiply 1 x 1  =  1;

   to get the denominator, multiply 5 x 3a  15a.
