b.l.m 3 years ago Find the value of y when x equals -4 in this equation. 5x + (-3y) = 13

1. Compassionate

-20 + (3y) = 13 Does that help?

2. Solmyr

same as last time

3. Compassionate

20 +(-20) + (3y) = 13 + 20 3y = 33 ... ?

4. Solmyr

5^-4 + (-3y) = 13

5. Solmyr

first do 5^-4

6. Compassionate

Solymr, that would be 5 * 5 * 5 * 5 = 0.0016 We want 5 * -4

7. Solmyr

well what im saying is 5 times -4 giving you -20

8. Solmyr

-20 + (-3y) = 13

9. Solmyr

then add 20 to both sides of the equations

10. Compassionate

-3y 30 --- = --- = ? -3 -13

11. Solmyr

no you divide -3 to both sides

12. Compassionate

It's an obvious typo.

13. Solmyr

-3y = 33 -------- -3 -3

14. Solmyr

oh my B :PP lol

15. b.l.m

okay what do i do?

16. Compassionate

Divide: 33 --- -3

17. Solmyr

so you get -11

18. Compassionate

x = -?

19. Solmyr

y = -11

20. b.l.m

11

21. Solmyr

hope it helped

22. Compassionate

Good luck.

23. b.l.m

is -11 fasure fasure right?

24. Compassionate

-11 is correct.
