might be able to help

Answer 6

okay

Answer 7

Are you trying to solve for x and y?

Answer 8

yes

Answer 9

Mhmmm, the easiest method to solve these, would be graphing, but the substitution and elimination method are also necessary to know

Do you know how to use either of them? substitution or elimination?

Answer 10

ya

Answer 11

i just struggle with substitution 2

Answer 12

at least i think this is substitution 2

Answer 13

I think that it would be easier to do elimination for this one.
Substitution means you'll have to do fractions lol

and what do you mean by 'substitution 2'

Answer 14

theres 2 different types of substitution

Answer 15

i will show you my paper

Answer 16

I suggest using elimination for this one

Answer 17

but y and x arent on the same side

Answer 18

You don't need them on the same side
As long as the x's are together, y's are together, it's good

Answer 19

....

Answer 20

3y=2x+15
2y=6x-18

I suggest multiplying the top equation, 3y=2x+15, by 3
By this, we can get 2x to 6x, and cancel x out
Can you do that?

Answer 21

yes i will try

Answer 22

Like, just multiply the whole equation by 3

3y(3) = (2x+15)3

Answer 23

i got
9y=6x+45
2y=6x-18

Answer 24

Yep, and so now, subtract the bottom equation from the top one

Answer 25

7y=x+27

Answer 26

Why do you still have x?

Answer 27

because 6-6 is 0

Answer 28

So, there's no x
It would be
7y=63
what is y

Answer 29

how did you get 63

Answer 30

i think i did osmethin wrong

Answer 31

45-(-18)

Answer 32

oh ok

Answer 33

y=9

Answer 34

Yep
and plug y into any of the 2 equations, just pick one, and then solve for x

Answer 35

I GOT 6

Answer 36

Yep

Answer 37

THANK YOUU 😢
