Question

Solve by substitution method
Solution Set is?

x+y=-9
y=-4x

Answer 1

since you are given y=-4x, you can substitute( -4x) for y in the other eq and then you will have an eq in one variable, x, which you can then solve for

Answer 2

yes i got that

Answer 3

x+(-4x)=-9
x-4x=-9
-3x=-9
x=3

Answer 4

so what did you get for x?

Answer 5

annas has it.

Answer 6

its a real simple question

Answer 7

(-4x)+y=-9

x=3

my comp is slow :(

Answer 8

but it says type in a orderd pair which is where i get lost

Answer 9

(x,y) replace

Answer 10

(3,-12)

Answer 11

so you just multiply

Answer 12

once you get the x value, plug it into either eq to get the y value. You then have the x and y value for the ordered pair

Answer 13

so you would put like -4(3)=-12

Answer 14

yes

Answer 15

I put 3 and -12 in and it said wrong hmmm

Answer 16

it worked i forgot the swiggless thingys
