I would subtract the 4y from the top equation, getting x= 4y + 9. Next I would plug x into the bottom equation (4y + 9 - y= 4) then solve it, and once I've got what y equals then I'd plug it into one of the two equations.

# data[].attributes.body
I would eliminate with multiplication because the y variables have oppsite signs.

subtract the x's

# data[].attributes.body
Both X's have the same coefficient so I would subtract the x's

# data[].attributes.body
I would Subtract the x's.

# data[].attributes.body
Because the X's are the same

You could use subtraction to cancel out the x's or use multiplication and times bottom one by 4.

# data[].attributes.body
I would eliminate the x's

# data[].attributes.body
Since the x is lined up it would make it so much easier.

I would multiply the bottom by 4
then add the two problems together to get rid of the y's

You could subtract and eliminate your x's or you could multiply your second equation by 4 and eliminate your y's. Either way, it's simple to see both.

# data[].attributes.body
You can just get rid of the x's

# data[].attributes.body
Just get rid of your x's. It's easy.

I would multiply the bottom equation by 4 and add getting rid of the "y".

# data[].attributes.body
x + 4y = 9

x  - y = 4

If you get rid of the x then subtract from there you would find that less work is involved in this than if you are doing substitution or multiplication.

# data[].attributes.body
I would solve it using elimination with multiplication because all you would have to do is multiply the bottom equation by 4.

# data[].attributes.body
I would multiply the second equation by 4 since "y" has opposite coefficients eliminating them.

multiply the second equation by 4
4(x-y=4)        OR use subtraction
(-)x-y=4

I would eliminate the x by subtracting leaving me with 5y=5.
Then I would divide by 5 leaving me with y=1. Then I would plug that in to the second equation giving me
x -1= 4. Then add the one giving me x=5 and a final answer of (5,1).

I would solve the linear systems using multiplication because I find that easier than using substitution. I would eliminate the y's first then go from there. You would have to go through a lot more steps with substitution, than if you were to use elimination.

# data[].attributes.body
I would solve it with elimination using multiplication, because if you multiply the second equation by four you can eliminate the y's. From that point, you can add the rest of the equations together and find your x value. Then you can solve for the y value, leading you to find your solution.

# data[].attributes.body
I would eliminate the "x"s by subtracting and by that I would get 5y = 5 and just go from there.

i would multiply the bottom equation by 4, eliminate my "y"s and go on from there. I would do this because the "y"s are already opposite signs so it would be easier.

# data[].attributes.body
I would Multiply the second equation by 4 because the y's are opposite and then they would cancel out then go from there.

# data[].attributes.body
I would use this method because multiplying the bottom equation by 4 is a lot easier than completly changing an equation.

# data[].attributes.body
I would use substitution because it is the easiest method. The equation on the bottom you could add the Y to the other side and there you have what X equals and you could use that for X in the top equation.

I would use elimination with multiplication because it would be easier to solve by multiplying the second equation by 4 and then I would just add the equation and cancel the Y's.
