## lizz123 one year ago Members pay a 48 dollars membership fee each year. The literal equation c=48y+0.99n represented the total cost c for a person who is a member of the music club for y years and who downloads n song. Solve the equation for y.

Well I know that i need to do opposite

5. lizz123

So, c=48y-0.99n

6. amistre64

my obscure thought process is to send the neighbors home, and then divorce the spouse ...

7. Anaise

weird

8. amistre64

we dont just change operations ... we have to add or multiply or 'do the same thing' to both sides of the =sign

9. amistre64

+.99n has no y in it ... i call it a neighbor; send them back home; add -.99n to both sides

10. amistre64

48y, 48 is married to y (multiplication and marriage start with 'm') .. divorce the 48 ... divide both sides by 48

11. amistre64

in the end, y has noone left around to bother them lol

12. lizz123

okay so would it|dw:1444503549001:dw|

13. amistre64

c = 48y+0.99n -0.99n -0.99n ------------------- c-0.99n = 48y

14. lizz123

ohh.. okay i see

15. lizz123

do I divide 48 both sides

16. amistre64

yes, in order to get y all alone ... we have to divorce the 48. i mean divide

17. lizz123

c-0.99n = 48y _______________ 48 48 $y=\frac{ c-0.99n}{ 48 }$

18. amistre64

thats perfect

19. lizz123

thanks.
