Question

equation one x+9y=7
equation two x=4-9y

To start using subtitution would I first add equation two into equation one (4-9y)+9y=7 ??
then doing order of opps I would get
-5y+9y=7 ?? I dont think I am doing this right .... help

Answer 1

llol

Answer 2

maybe...why?

Answer 3

lol

Answer 4

jking

Answer 5

is that you in the photo?

Answer 6

subtitute x=4-9y in the 1st eq
4-9y+9y=7
4=7 not true

Answer 7

maybe y??

Answer 8

LOL.

Answer 9

No solution.

Answer 10

Angela, how do you figure out y?

Answer 11

you can see that the slope are same.

Answer 12

and you can also see that the y-intercepts of each equation aew differnt.

Answer 13

are different*

Answer 14

sub 4-9y into first equation

Answer 15

Agree ^^ (is this wht u usually type Saif? )

Answer 16
