Answer:
Step-by-step explanation:

On the left-hand side of the equation, both terms have a common factor of
, so we can pull that out:

We can now create two equations from this to solve for
:


The first equation doesn't need any further work, but the second equation can be reduced by substracting
from both sides to get
by itself on the left-hand side:

Therefore, the two solutions to the problem are
