Answer 2

What is the solution to the following system of linear equations, using substitution?
3x + y = −9

A. (−3, −2)
B. (−3, 0)

Can you show me how to do it? I don't want an answer I wanna under stand it. Do any of them cancel each other out or something?

Substitution is different.

Solve for either "x" or "y". You can chose, tag me when you're done. FYI, it can be either equation you solve for.
