, 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.
