## DJBreezy one year ago What is the solution to the systems of equations represented by the 2 equations? y = 4x + 3 y = -x - 2 A. (1, 7) B. (-1, -1) C. (2, -4) D. (-3, -9) @M_lowreen

HINT: substitute the value of y from the 2º equation into the first one

4. Nnesha

replace y in first equation by 2nd one |dw:1433538776999:dw| after that simple algebra solve for c

5. Nnesha

x* not c

6. DJBreezy

i personally think the answer is C.

7. anonymous

no

8. Nnesha

how did you get C ?

9. DJBreezy

^^^^^ tried the question u gave me already..

10. Nnesha

C is not correct try again show ur work plz

11. DJBreezy

12. Nnesha

is that a educated guess or you solved it ?

13. DJBreezy

Educated guess....it was between c and B

14. Nnesha

how about to solve it instead guessing $\huge\rm -x-2=4x+3$ solve for x or to check an answer replace x and y by order pair if both sides are equal then that order pair is ur answer

15. DJBreezy

X= -1 @Nnesha

16. Nnesha

yes right $\huge\rm -(-1)-2=4(-1)+3$ replace x by -1 solve both sides if both sides are equal then your answer is right :-)

17. DJBreezy

idk how to do this part..

18. DJBreezy

i get confused here

19. Nnesha

yes right $\huge\rm -(-1)-2=4(-1)+3$ solve left side -1 times -1= ?? and then add -2

20. DJBreezy

Oh its B

21. Nnesha

my questions is both sides are equal or not ? if both sides are equal then yes if both sides are not equal then no yes right $\huge\rm -(-1)-2=4(-1)+3$

22. DJBreezy

Yes....My cousin just helped me with it....

23. Nnesha

say thanks for DA to PA(ur cousin) alright great job!

24. DJBreezy

thx
