Add the 1st equation to the negative of the 2nd equation.
What do you get?

Y= -2x + 1
and
Y= -4x - 1

Y= -2x + 1
and
Y= -4x - 1

yeah

So what do you think we should do with that last equation?

solve it or simplify it

Ok, try it out - I'll watch and help

are you tring to put it into y= form?

How can we simplify this -
-2x -(-4x) + y - y = 1 -(-1)
?

-2x+y=1

See the y - y will cancel to become zero
$$
-2x -(-4x) + 0 = 1 -(-1)\\
$$
What's else can we do?

subtract the values and get -6x

Close
The -(-4x) becomes just 4x:
$$
-2x +4x + 0 = 1 -(-1)\\
$$
Now what?

What is -2x + 4x ?

2x

yes!
So now we have
$$
2x+0=1-(-1)
$$
What's can we do next?

2x+0=-2

-(-1) = 1
Remember, negative of a negative number makes it positive
Try again

2x+0=1

$$
2x+0=1-(-1)=1+1
$$
Do you see that?
What's next?

2x+0=2

yes!
Ok, what do we do now?

subtract 0 from both sides and get
2x=2

What next?

the answer choices are
A. (3,1)
B (-1,3)
C (-1,-3)
D (1,3)

We need x by itself, what do we need to divide out on both sides to make 2x equal to just x ?

2 divided by both sides

x=0

x=1

$$
-2\times 1 + y = 1
$$
So now what is y?

-2y=1

$$
-2\times 1 + y = -2+y=1
$$
See that?

yeah

How do you move the -2 to the other side of the equal sign?

im so confused this isnt leading to any of the answer choices

and i have so many more questions in so little time

Add 2 to both sides of this equation
$$
-2+y+2=1+2
$$
What does this give us?

-2 + 2y = 3

Almost there
$$
-2+2+y=3
$$

What's -2 + 2?

y=3

Yes!
So now you know everything.
x=1
y=3
(1,3)

oh thats make so much sense thanks so much

When you do one on your own, all the others will be like adding 1+1=2

do another on your own
right here

Have some courage my friend, everything takes time -- don't worry about the little things.
