Question

Solve for p.

3(p+q)=p

A) q=-2/3p
B)q=-3/2p
c)p=-2/3q
D)p=-3/2q

I really need some help on this kind of question because I don't really understand it.

Answer 1

3p+3q=p
2p=-3q
p=-3q/2

Answer 2

you need to multiply out on the left first, using the distributive law
i.e. turn \(3(p+a)\) in to \(3p+3q\) then start with
\[3p+3q=p\]

Answer 3

you want now to get all the \(p\) stuff on one side of the equal sign, you can do that by subtracting \(3p\) from both sides, giving you
\[3q=-2p\]

Answer 4

final step to get \(p\) by itself is to divide both sides by \(-2\) to give a final answer of
\[-\frac{3}{2}q=p\]

Answer 5

Alright, thank you very much. I kinda get it now. @satellite73

Answer 6

kinda is close enough i guess
do a couple more and you will see it
it is just like solving
\[3(2+x)=x\] but with a \(q\) instead of a \(2\)

Answer 7

yw
how bout those pirates?!

Answer 8

Yeah, I got to get better at this. I am good with equations that does not have so many variables in them. Anyways, the Pirates won last night. The score was 3-0, I think.

Answer 9

(B.)
