## bugsey7 3 years ago Some Algebra 1 Questions.. Did I get these right? What is the value of the y variable in the solution to the following system of equations? 3x - 6y = 3 7x - 5y = -11 is it "-2"? What is the value of the x variable in the solution to the following system of equations? 2x - y = 6 4x - 2y = 12 is it "x can be any number as there are infinitely many solutions to the system." or "0"? What is the value of the x variable in the solution to the following system of equations? 4x + 2y = 12 x - y = 3 Is the answer "3"? THANKS

I figured someone could also check these for me? If you want, they should be easy enough. The graph of a system of equations will intersect at more than 1 point. Always The graph of a system of equations with the same slope will have no solutions. Never (or is it Sometimes...?) The graph of a system of equations will intersect at exactly 1 point. Sometimes

#1 is correct

3. Ledah

I would assume if you did these the exact same way. you got it down. So its safe to say your correct

4. bugsey7

Well, sometimes I do problems and I mess up something really simple or I use the same method and screw up, soooo it's not safe to say I'm correct XD

5. Ledah

graph of a system. same thing applies if you know this well enough. its always best to go with your first answer is what my american government teacher said..

6. bugsey7

I know that, but sometimes I just need to be checked. I get weird with math. o:

7. Ledah

haha don't worry I'll see if somebody can check these @timo86m Please check these for her :o

8. bugsey7

okay

9. timo86m

3x - 6y = 3 7x - 5y = -11 is it "-2"? yes but plug that back in to either equation to get the other :) x = -3, y = -2 good job :)

10. timo86m

oh wait you want just the y :D nvrmnd

11. timo86m

you are right good job :)

12. bugsey7

On all of them? o.O

13. timo86m

2x - y = 6 4x - 2y = 12 x=x

14. Ledah

Told you bugsey o_o

15. timo86m

doing one by one :)

16. timo86m

4x + 2y = 12 x - y = 3 x=3

17. timo86m

you are right on all of them :D

18. bugsey7

sweet! :D Thank you!

What is the value of x in the solution to the following system of equations? x − 2y = 2 3x + y = 6 @Sparklestaraa can you help

21. triciaal

this is such a long thread too many questions for one post!! parallel lines have the same slope no solution
