Question

For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

-x + 2y = -6
3x + y = 8

Answer 1

-x+2y=-6
-x=-2y-6
x=2y+6

Answer 2

Lifesaver :)

Answer 3

Do you realize there are many ways to do this system by this method?

Answer 4

No I didn't know that, I haven't learned this yet at all. I'm taking some sort of "pretest". and I got -2y + 6 somehow

Answer 5

well do not test out of systems, it is important to learn all of the different methods.
This will help you in the future math courses.

Answer 6

Thank you :)

Answer 7

anytime :)
