Imagine you are teaching a younger student how to factor. Describe in full sentences what you would say to teach the young student how to factor the trinomial + 4x - 21 into (x - 3)(x + 7). Your description must include at least 3 different steps.

Use the elimination method to find the solution to the system of equations. 2x - 3y = -9 -x + 3y = 6
