Please help. I will fan and give medal to whoever succeeds in helping me.
For the following system, if you isolated y in the first equation to use the Substitution Method, what expression would you substitute into the second equation?
4x − y = 8
2x + 3y = 9
8 − 4x
8 + 4x
−8 + 4x
−8 − 4x

Best ResponseYou've already chosen the best response.0Yep @warningiflirt is right. 1 means the opposite. So take the opposite of 84x

Best ResponseYou've already chosen the best response.0y = (8 4x) y = (84x) If you know how to distribute it makes it y = 8 + 4x
