Answer 3

please help me and @M_palomares and @iamabarbiegirl and @IMANINJA127

Answer 4

i see

Answer 5

Look above at the link so that you will know what coincident lines are.

Answer 6

Then, you will have an idea about the missing coefficients.

Answer 7

oow

Answer 8

Look at the two equations in the post.

For the x coefficients, what do you do to 3 to get 9. Multiply it by what?

Answer 9

@ellenalexis11

Answer 10

ok

Answer 11

3

Answer 12

I am trying to help you and you are tagging others to help you without even giving me a chance.

Answer 13

right you have to multiply by 3

Answer 14

it wont happen again sorry

Answer 15

Look at the coefficients of the y terms in the given equations. The first equation has a y term with an understood coefficient of 1. So, multiply the 1 by what to get the missing y coefficient of equation 2?

Answer 16

:/ im stuck here i need your help

Answer 17

What did you multiply by on the x terms - same number to multiply 1 by.

Answer 18

and after that

Answer 19

do i do it again

Answer 20

3x + y = 7
9x+ ( 3 ) y = ( )

Answer 21

And, what goes in the last "blank?"

Answer 22

4 right

Answer 23

No.

Answer 24

>>>> right you have to multiply by 3

Answer 25

Every member of this first equation is multiplied by 3.

3x+y=7

Answer 26

What is 7 times 3 =

Answer 27

21

Answer 28

Right

Answer 29

3x + y = 7
9x+ 3 y = 21

Answer 30

so it will look like this 9x+3y=21

Answer 31

ok thanks

Answer 32

The two equations have the same graph.

Answer 33

It looks like that but the entry required on the computer answer may be must those coefficients. You'll have to look and determine that.

Answer 34

ok
