Question

Which is the solution of the system?
A. (-4,2)
B. (-3,1)
C. (-3,-5)
D. (4,-6)

Answer 1

do i use distributive property???

Answer 2

I don't really know what your question is asking

Answer 3

yeah nvm i understand it now that i really look at it..its all good

Answer 4

\[\frac{ (x+y) }{ (2x-3y) } = -\frac{ 2 }{ 9 }\] is the problem this?

Answer 5

Can you just take a picture of it and upload it

Answer 6

Oh, that makes sense, they are two different equations right?

Answer 7

Yeah!

Answer 8

so basically i just use distributive property?

Answer 9

Ok so you have two equations, \[x+y=-2\]
\[2x-3y=-9\]

No not quite, so does it ask for any methods, like elimination, substitution, matrices?

Answer 10

it asks what the solution is

Answer 11

Ok, we can use any method then

Answer 12

im gonna give you a medal just cuz youve been the most help ive had since ive gotten on here

Answer 13

Lets use substitution, so to do this problem, we want to isolate one of the variables in one of the equations and plug it into the second equation, that will help us find the x value and then we can go back and find the y value. We could also take your options in to our advantage and do it the lazy way but I don't think you will learn that way.

Answer 14

Ok I think drawing it out will make more sense, first you want to label the equations

Answer 15

Did you read what i said?

Answer 16

Hey, yes I did thanks :)

So lets do this problem now, pick one of the equations and one of the variables to isolate in that equation.
