## mckenzieandjesus one year ago What is the solution of the system of equations? y = –4x + 10 y = –2x – 6 (–2.67, 20.67) (–22, 8) (–2, –2) (8, –22)

1. mckenzieandjesus

@Mehek14 do you know to do this?

2. Mehek14

yes I do :]

3. mckenzieandjesus

ok :)

4. Mehek14

put the value of y in the second equation for y in the first equation $$\bf{-2x-6=-4x+10}$$

5. mckenzieandjesus

ok

6. Mehek14

now solve for x

7. mckenzieandjesus

so the -2x-6=-4x+10 is how u add y in the second equation to the first?

8. Mehek14

I put the second equation for y in the first equation

9. Mehek14

so solve for x

10. mckenzieandjesus

6?

11. Mehek14

|dw:1443827313138:dw|

12. Mehek14

my ad $$\bf{-16=-2x}$$

13. mckenzieandjesus

ohh ok

14. mckenzieandjesus

I forgot how to do it, thanku

15. Mehek14

now can you do the last step?

16. mckenzieandjesus

what is the next step?

17. Mehek14

-16=-2x how can you solve for x?

18. mckenzieandjesus

multiply something?

19. Mehek14

divide -16/-2 = x

20. mckenzieandjesus

-8

21. Mehek14

negative/negative = positive

22. Mehek14

so +8

23. mckenzieandjesus

ok

24. mckenzieandjesus

and y is -22?
