Question

solve the system using the elimination method 3x+2y=-2 and 6x-y=6

Answer 1

Multiply the first equation by -2. This makes it so that the x's cancel out (-6, & 6)
Then solve for y.

Answer 2

Did you get -6x-4y=4 ? With that first step.

Answer 3

I got y=2?

Answer 4

so yes then may i ask what would the next step be?

Answer 5

Right! Now plug 2 back into 3x+2y=-2 for y .

Answer 6

And solve for x *

Answer 7

3x+4y=-2? I think I'm lost lol?!

Answer 8

That is one of the original equations. You can use either, I just picked that one.

Answer 9

you can plug it into 6x-y=6 instead. Both work

Answer 10

ok so what would x =?

Answer 11

Well, when y=2 , plug it it to solve for x.
3x+4(2)=-2

Can you solve from x from this point?

Answer 12

3x+8=-2 so then you would subtract 8 to both sides?

Answer 13

yes

Answer 14

so therefore x=2?

Answer 15

y actually equals -2

6x-y=6
-6x-4y=4
-5y=10
divide both sides by -5
y=-2 (what we said originally was wrong, y is not 2)

Plug -2 back into 3x+4(-2)=-2
3x-8=-2
add 8 to both sides
3x=6
divide both sides by 3
x=2

Makes more sense. Yes x is 2

Answer 16

omg yay that's how its done!!!! thanks! I got that!! :) girl, idk if this is a personal question or not but do you happen to have a facebook?

Answer 17
