Question

Someone should really help me! (: I typed up the question already.

Answer 1

2x+y=1
-3x+y=-9
I already subtracted the bottom equation from the top one. I just don't know what to do next

Answer 2

multiply 1 of them by -1
that will make it so u can cancel out the y

Answer 3

and than?

Answer 4

which 1 did u multiply by -1

Answer 5

5x=10

Answer 6

ya so then u divide both sides by 5

Answer 7

of 5x=10?

Answer 8

ya so u go 5x/5=10/5

Answer 9

so y =2

Answer 10

no x=2
cuz 5x/5 cancels out to x
and 10/2 simplifies to 2
soooo
x=2

Answer 11

So what does y=?

Answer 12

so plug in x=2 to the 1st equation so it would look like 2(2)+y=1
and then u solve that

Answer 13

so x=6?

Answer 14

no...
so 2(2)=4 right

Answer 15

Yeah y = 2 so 4+2=6

Answer 16

no y doesnt =2
its 4+y=1
-4 -4
y=1-4
y=?

Answer 17

did u get it?

Answer 18

-3?

Answer 19

yup!! good job!! :)

Answer 20

Amen! Haha

Answer 21

do ya understand how to do it now?
