Yacoub1993 2 years ago Solve the equation for y. Then graph the equation. 5x – 4y = 12 A. y = -5/4x - 3 B. y = 4/5x + 3 C. y = 5/4x - 3 D. y = -4/5x + 3

1. manishsatywali

take the terms of x on right side first

2. manishsatywali

do it asap

3. Yacoub1993

-4y=12-5x

4. manishsatywali

divide both sides by -4

5. manishsatywali

tell me wat u got

6. Yacoub1993

i got y=$\frac{ 12-5x }{-4 }$

7. manishsatywali

check wid the options u hav mentioned asap

8. manishsatywali

asap

9. Yacoub1993

$\frac{ -4y }{-4 }=\frac{ 12-5x }{-4 }$

10. manishsatywali

perform the division quickly

11. Yacoub1993

didnt get from here

12. Yacoub1993

@manishsatywali i didt get it from here Any Idea

13. manishsatywali

|dw:1359462679400:dw|

14. Yacoub1993

still have no idea how this works

15. manishsatywali

tell me where u stuck??????

16. Yacoub1993

calculating the equation u gave me

17. Yacoub1993

from were did u get the cube beside $\frac{ 12^{3} }{ -4 }$

18. manishsatywali

it's nt the cube dear see the fig. i m redrawing it ....i hav cancelled 12 from 4 since 4*3 =12|dw:1359463192376:dw|

19. Yacoub1993

ok then

20. Yacoub1993

OK IS IT $y=3-\frac{ 5 }{ 4 }x$

21. Yacoub1993

sory like this is correct right$y=-\frac{ 5 }{ 4 }-3$

22. manishsatywali

u forget x mention it

23. Yacoub1993

$y=-\frac{ 5 }{ 4 }x-3$

24. Yacoub1993

correct

25. manishsatywali

yup as always...dear u got it right

26. Yacoub1993
