## anonymous one year ago if 2/3 p + 6 =7/6 p , what is p?

• This Question is Open
1. LynFran

bring p to 1side of the equation and solve

2. LynFran

hint: subtract 2/3p from both side of the equation

3. LynFran

so we have 6=7/6p-2/3p

4. jdoe0001

hint: multiply both sides by "p"

5. anonymous

r u guys sure?

6. anonymous

@jdoe0001 u r wrong

7. anonymous

if we follow what @lynfran stated we can arrive at the answer

8. jdoe0001

hmm? is the fellow even here? he doesn't seem to be saying anything

9. anonymous

idk

10. LynFran

$\frac{ 2 }{ 3p }+6=\frac{ 7 }{ 6p }$$6=\frac{ 7 }{ 6p }-\frac{ 2 }{ 3p }$$6=\frac{ 7-4 }{ 6p }$$6=\frac{ 3 }{ 6p }$$6=\frac{ 1 }{ 2p }$multiply both side by 2p we get $2p*6=1$\...solve for p..

11. anonymous

@LynFran woudnt it be like this? $\frac{ 2 }{ 3 }p+6=\frac{ 7 }{ 6 }$ $6=\frac{ 7 }{ 6 }p-\frac{ 2 }{ 3 }p$ (you subtract 7/6 - 2/3 and get 1/2 ) $6=\frac{ 1 }{ 2 }p$ $p=?$

@LynFran

13. LynFran

no... then u will have p = 12 thats not the answer...lol

14. anonymous

no?

15. LynFran

continue frm where i left off 2p*6=1 12p=1 divide both sides by 12 to get the value of p...

16. anonymous

ok

17. anonymous

but that would not check out right. you would get, if you plug in 1/12 in for p, 109/18 = 7/72. wheras if you plug in 12 (the answer that i got ) you would get 14 = 14 clearly checking out.

18. anonymous

or am i missing something?

19. LynFran

$\frac{ 2 }{ 3(\frac{ 1 }{ 12 }) }+6=?$

20. anonymous

14

21. anonymous

what ???

22. LynFran

$\frac{ 7 }{ 6(\frac{ 1 }{ 12 }) }=?$

23. anonymous

ok idk how you did that

24. LynFran

lol..

25. anonymous

but then woudnt that mean that im also right?

26. anonymous

couse idk what i did wrong

27. LynFran

ok lets check...$\frac{ 2 }{ 3(12) }+6=?$$\frac{ 7 }{ 6(12) }=?$

28. LynFran

u was suppose to find a common denominator $\frac{ 7 }{ 6p }-\frac{ 2 }{ 3p }$

29. anonymous

wasnt the question $\frac{ 2 }{ 3 }P+6=\frac{ 7 }{ 6 }P$ but you solved for $\frac{ 2 }{ 3P }+6=\frac{ 7 }{ 6p }$

30. anonymous

isnt there a differance?

31. LynFran

so $\frac{ (7*1)-(2*2) }{ 6p }$

32. anonymous

$\frac{ 1 }{ 2p }$

33. LynFran

and remember p" is in the denominator so we multiply by 2p to both sides of equation

34. LynFran

so 2p*6=1

35. anonymous

but in the original problem how do we know that the p was on the denominator?

36. LynFran

well it looked so to me lol...could be wrong then...

37. LynFran

if its not then ur right..

38. anonymous

i understand what you were doing tho

39. LynFran

ok..

but tylerhuang is offline hmm...
