The first step in solving an equation like this is to get all of the terms containing a variable on one side of the equation, leaving the constant terms on the other side.
So let's add
to both sides of the equation, thus:
, so we can write:
Also,
, so we can write:
The last step is to get rid of the coefficient on the variable. In this case, we can divide both sides of the equation by
Since we know that
we can write:
, which can also be written
or
. Any of which are acceptable representations of the solution, though the last one is probably what your instructor wants.
