pooja195 · Answer

elimination might be easier here

anonymous · Answer

that is what i think

pooja195 · Answer

ok multiply the top equation by -2 to make the equation opposite

pooja195 · Answer

$$-2(3x - 2y = 15)$$

anonymous · Answer

see here is my question

Determine which system below will produce infinitely many solutions.

2x + 5y = 24
2x + 5y = 42
-------
3x - 2y = 15
6x + 5y = 11
-------
4x - 3y = 9
-8x + 6y = -18
-------
5x - 3y = 16
-2x + 3y = -7

i know A isn't it, but i am trying to solve for B using the elmination method. last people tried but gave some weird hard explination not using any of those two methods

anonymous · Answer

ok that is what I did at first, so that means

3x - 2y = 15  ->  6x + 4y = -30

right

@iambatman help???

pooja195 · Answer

nope and sorry for the late response this site it laggy >_<

anonymous · Answer

wait would the 4y be -4y

anonymous · Answer

can we make a twiddla or something to work on?

pooja195 · Answer

pm me the link ill help u there

anonymous · Answer

would be a whole lot easier than here right now

pooja195 · Answer

-6x+4y=-30
