Question

6x - 2y=4 y + 2=3x.....I need help showing that this is a dependent equations.

Answer 1

Ok first we need to solve for x or y in one equation

so lets start off by doing this making y+2=3 into y=3x-2

Answer 2

Now we know what y equals so we then plug in y into 6x-2y=4

Answer 3

Are you getting it so far?

Answer 4

so i plug y=3x-2 after the 2 in 6x-2y=4?

Answer 5

yes :) so it will be 2(3x-2)

Answer 6

Because y =3x-2 you can plug in that after the 2

Answer 7

Now solve for x

Answer 8

and tell me what you get

Answer 9

x=0

Answer 10

ok lemme check your awnser

Answer 11

Yes that is correct :D

Answer 12

So this proves that one equation is dependant on the other equations set of values

Answer 13

then i plug the 0 for x in 6x-2y=4 to solve for y?

Answer 14

correct

Answer 15

so how would it look like when I graph it?

Answer 16

0=3x-2
2=3x
x=2/3

Answer 17

Lemme refresh my memory a bit sorry

Answer 18

Actually we are sposed to solve both equations for Y, silly me. Ok so we know y=3x-2 but also we need to solve for y in 6x-2y=4

So we change 6x-2y=4 to -2y=4-6x

Then we divide both sides by -2
to get y=3x-2


So since they both are the same line you just graph 3x-2

Answer 19

Sorry about that I was in the wrong mindset

Answer 20

it's ok

Answer 21

So it should look something like this

Answer 22

Because both equations produce the same line and are consistant so therefore they are dependant of eachother

Its a phrase you can use if you are instructed to explain your awnser

Answer 23

thanks so much!

Answer 24
