Answer 1

just need a walkthrough or can I just this away?

Answer 2

Wym?

Answer 3

I have no idea how to do this .. Lmfao 😂

Answer 4

I know how to

Answer 7

Can you try to explain? :)

Answer 8

ill try to explain as well as I can

Answer 9

Okay thank you.

Answer 10

so first we have x -3y,
to help find y, we also have 2x -7y

Answer 11

Ok

Answer 12

try to finish this:
x−3y=−6
(x−3y)+(−x)=−6+(−x)
x−3y−x=−6−x

Answer 13

3y = -6-x ?

Answer 14

this is a screenshot of all the work explained out

Answer 15

x=3y-6
2(3y-6)-7y=10
6y-12-7y=10
-y-12=10
-y=22
y=-22
then
x=3*-22-6
x=-66-6
x=-72

Answer 16

one thirdx + 2 once you simplify it

Answer 17

Oh ok

Answer 18

And now for the other one?

Answer 19

I have to go, but try to figure out how I worked it through in that screenshot k?
