Using substitution, could someone please help me with this system?
–y + 3x = 6
y = –6x + 12
So far I've gotten:
Substituting the second equation into the first you get
(6x+12) + 3x = 6
Which can be solved for x after finding x you can use the second equation above directly to find y

Best ResponseYou've already chosen the best response.0Well, I had help with that part, but I can't figure out what to do next. I tried using my textbook, but it was a bit confusing, because they showed you what to do, but didn't explain it.

Best ResponseYou've already chosen the best response.0Ok, first let's distribute that (6x+12) Can you do that?

Best ResponseYou've already chosen the best response.0Think of it this way: ()(6x) & ()(12)

Best ResponseYou've already chosen the best response.0Because negative times negative equals a positive 6x + 12?

Best ResponseYou've already chosen the best response.0yes, very good so we have 6x12+3x=6 What will you do next?

Best ResponseYou've already chosen the best response.0Okay, so how would I go about solving for x? Also, thank you for the medal.

Best ResponseYou've already chosen the best response.0We have x on one side, can we get non xvalues on the other side?

Best ResponseYou've already chosen the best response.0You would add 12 + 6? Then get 18, divided by 9x would equal 2.

Best ResponseYou've already chosen the best response.0What are you going to do with that x=2?

Best ResponseYou've already chosen the best response.0Substitute 2 for x in either equation and solve for y? Sorry, my computer is slow sometimes.

Best ResponseYou've already chosen the best response.0What would I do next?

Best ResponseYou've already chosen the best response.0same that you did when you had 9x12=6 and solved for x. now we are going to it for y

Best ResponseYou've already chosen the best response.06  6 = 0 So y, would be 0?

anonymous

Best ResponseYou've already chosen the best response.0Then I would substitute 0for y, and get 0 + 6 = 6.

Best ResponseYou've already chosen the best response.0Correct: So your Answer is: X=2, y=0

Best ResponseYou've already chosen the best response.0As long as you get a correct statement when you plug them both back in, like you showed 6=6 and not get something like 7=6, then we would have a problem.
