In this week of math i learned how to use elimination to solve easy systems very fast and efficient.
you can see in the photo that i start with the system at the top. i chose to use elimination because as you can see the 2x and -2x. when you add them together they become 0. So that means when i add everything together it will go away and isolate y instantly, so that i end up with just needing to divide the 4 away from the y. that’s it!!
