Question

"What is the solution of the following system?"
-3x - 2y = -12
9x + 6y = -9
@jigglypuff314

Answer 1

for this, you can divide through by 3 for the second equation :)

Answer 2

Divide the second equation by 3???

Answer 3

Woot! Okay.

Answer 4

I got 3x+2y=-3

Answer 5

Great! :D wow, you're getting good at this! :)

now you can do this by elimination
-3x - 2y = -12
3x + 2y = -3

Answer 6

do i add or subtract? And I can cross out -2y and +2y right?

Answer 7

oh wait O_O
when you see that by doing that you get no variables left and unequal numbers on the right, it means that the two equations are parallel

Answer 8

OH ! so it's has infinitely many solutions ?

Answer 9

hmmm parallel lines would never intersect so no solutions

but if the same thing happened on the left, but the right were Equal. then since they are the same equations, there would be infinitely many solutions

Answer 10

Oh okay, so the left is no solutions, the right is infinitely many?

Answer 11

mmmm sorry if I was confusing u
I meant that for this you were left with
not variables on the left, but since -12 and -3 are different
the system would be of parallel lines, which never intersect so have no solutions

if you had numbers like 3 and 3 on the right
then the system would be of same lines, which overlap entirely and have infinite solutions

Answer 12

Okay! Gotcha, I understand! Thank you so much for all your help. If I need anything, I'll let you know. :)

Answer 13

Okay :) I'm glad I could help <3
