In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value, . In this case, we need to isolate in the first equation so that both equations .
With this, we now know that both and are equal to , so we can set them equal to each other.
