Help!?
Determine which system below will produce infinitely many solutions.

-6x + 3y = 18
4x - 3y = 6
2x + 4y = 24
6x + 12y = 36
3x - y = 14
-9x + 3y = -42
5x + 2y = 13
-x + 4y = -6

Which one can you times the first equation by -3 and make it equal to the second one?

anonymous · Answer

Uhm well I don't know off the top of my head I would have to look at them first @haleyelizabeth2017

haleyelizabeth2017 · Answer

Okay....I will give you a hint. It is normally (the first equation) 3x-y=14

anonymous · Answer

Okay well I figured that out

So there ya go :)

wait... that's the answer? c?

haleyelizabeth2017 · Answer

You can tell it will be that one because if you multiply the first equation by -3, it will be the same as the second equation, which in turn, you will get infinitely many solutions.
