2x+3y=1 and y=-2 - 9 solve using linear combination method. explain steps.

Step-by-step explanation:

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.
