Question

4x + y = -1
3x + 2y = 8

Answer 1

Are these two seperate equation?

Answer 2

I don't think so, I have to find the points for the graph.

Answer 3

Ok

Answer 4

I have
4x = -1 - 4
(-1 - 4) + 2y = 8
So far but I don't know if I'm doing it right. Or if I am doing it right what to do after that.

Answer 5

So what we have here is :
4x + y = -1
3x + 2y = 8
So What i think you havta do is solve by elimation
So to do this we have to do the following:

Answer 6

We multiply the equation by its coefiicant

Answer 7

So:
-3(4x+y=-1)
4(3x+2y=8)

Answer 8

Can u Solve that?

Answer 9

I can try.

Answer 10

Here is a more sensible approach.
From the first equation, y = -1-4x
Replace y in the second equation with -1-4x

Answer 11

\[3x+2(-1-4x)=8\]

Answer 12

\[3x-2-8x=8\]

Answer 13

\[-5x=10\]

Answer 14

\[x=-2\]

Answer 15

\[y=-1-4x\]

Answer 16

\[y=-1-4(-2)=-1+8=7\]

Answer 17

Solution is (-2,7)

Answer 18

Could I email you the graphs I can choose from to see which one would be correct? and thank you!

Answer 19

Never Mind I think I know which one is right!

Answer 20
