## Discord 3 years ago I need help in answering this question: x - 3y = 9 x + 2y = -1 I have to solve by substitution.

1. iheartfood

ooooh i just got help with stuff like this!!

2. iheartfood

so you can find x first...

3. iheartfood

|dw:1348537411640:dw|

4. iheartfood

so there's ur value of x :) and substitute into an equation for y :)

5. Discord

How do you get -3y = 9 to 3y - 9?

6. iheartfood

|dw:1348537454761:dw|

7. iheartfood

so there is ur value of y :)

8. iheartfood

oh okay lemme show you how.... i got that..

9. iheartfood

so the original equation is |dw:1348537532420:dw|

10. iheartfood

you following?

11. iheartfood

@Discord do u understand this?

12. Discord

Oh right sorry

13. Discord

Following

14. iheartfood

it's all good just wondering :)

15. iheartfood

okay so you do this then..|dw:1348537640529:dw| it's the same thing but u just isolated the x. u follow?

16. Discord

Ohh thank you.

17. iheartfood

okay so then look above... that's when you plug it in for y... do you understand how i got y??

18. Discord

Yeah. It makes sense.

19. iheartfood

okay so then you're not done because now you need to solve for the official official value of x... and i wrote official twice on purpose :) lol tehehe

20. iheartfood

so plug in y=-2 into any equation to solve for x.

21. Discord

Oh okay. Carry on

22. iheartfood

|dw:1348537782220:dw|

23. iheartfood

so x=3 and y=-2.... do u understand now? :D

24. Discord
