Question

What is the solution of the system?
y=-3x
3x+2y=6
A. (2,6)
B. (-1,3)
C. (-2,6)
D. (1.5, -4.5)

Answer 1

you have got to be kidding...

Answer 2

y=-3x
3x+2y=6

3x+2(-3x)=6
3x-6x=6
-3x=6
x=-2

can you solve for y?

Answer 3

Hint: plug in the x value that you got, into the first equation.

Answer 4

Is y 6?

Answer 5

Good job!

Answer 6

so if
x=-2
y=6

and the discordant is (x,y)
your's would be (-2,6)

MAKES SENSE?

Answer 7

I meant coordinate, not discordant, sorry.

Answer 8

Yes! Thank you!

Answer 9

Anytime!
