Question

2. How many solutions does this system have?

2x + y = 3
6x = 9 – 3y (1 point)

Answer 1

Well,you can solve it and check.

There are a number of methods you can use

1)Elimination
2)Substitution

Answer 2

I was not in class for this whole past week. I have been very ill. I dont know what any of that means.

Answer 3

Well lets see it like this

2x+y=3---(1)
6x+3y=9--(2)

Multiply Eq(1) by 2.

And,

then subract these equations.

Answer 4

Okay, I am still kind of confused. Im sorry. /:

Answer 5

Did you Multiply Eq(1) by 2,What did you get.

Answer 6

No, hold on I will do that now.

Answer 7

ok.

Answer 8

Take your time...

Answer 9

I am lost. I am horrible at math. ...

Answer 10

What did you get ?

Answer 11

Nothing. . . /':

Answer 12

I can't do it. It is all giberish to me...

Answer 13

So,
you are doing something you dont know.

Lets start working on your basics then or Lets use the other method

what do you think ?

Answer 14

Yes, and it doesnt matter.

Answer 15

X=3/2 and y=0

Answer 17

2x + y = 3--(1)
6x = 9 – 3y--(2)

(1)=)

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


Now put Eq(3) or y in Eq(2)

Answer 18

That wasnt a direct answer... The answer will be either, 1, none, 2 or infinite. So @chow is okay..

Answer 19

thanks Kierstan...I don't have energy to type total derivation..

Answer 20

You're welcome.

Answer 21

@KierstanDanielle

If you have the options then you can actually try putting your answer options and checking if

L.H.S=R.H.S

If L.H.S=R.H.S

then that is the correct answer option.

Answer 22

@chow I hope you understood what i said.

Answer 23

yes..

Answer 24

What does L.H.S. and R.H.S mean?

Answer 25

Left hand side = Right hand side

Answer 26

oh. hahha

Answer 27

@chow Thanks a lot for understanding.

Answer 28

Okay, I think I might have the answer. Thanks for helping !

Answer 29

Your'e welcome.
