We want to get 'p' by itself, so the first step would be to get rid of 9..so what do we do to it?

anonymous · Answer

@Holt

igreen · Answer

Btw, nice username $\large\ddot\smile$

anonymous · Answer

thankyou!! :D

igreen · Answer

We want to do the opposite, And it's being subtracted..so what's the opposite of subtraction?

anonymous · Answer

add

anonymous · Answer

addition

igreen · Answer

Yes, so we add it to both sides.

$\sf \dfrac{p}{5} - 9 + 9 = 14 + 9$

The 9's on the left cancel out, giving us:

$\sf \dfrac{p}{5} = 14 + 9$

Can you add that?

anonymous · Answer

uh......

igreen · Answer

$\sf 14 + 9 = ~ \! ?$

anonymous · Answer

23

igreen · Answer

Yes, so we have:

$\sf \dfrac{p}{5} = 23$

Now do the opposite of dividing 5..multiply.

calculusxy · Answer

So now you have:
$$\frac{ p }{ 5 } = \frac{ 23 }{ 1 }$$

calculusxy · Answer

That's how I like to think of it -- as a proportion.

anonymous · Answer

okay so I multiply what numbers again? @holt you have an answer??

igreen · Answer

Yes, that's a good way to look at it..then you can just cross multiply.

calculusxy · Answer

5 x 23 = p x 1 (which is in other words p)

calculusxy · Answer

Rewrite:
$$5 \times 23 = p $$

igreen · Answer

$\sf \dfrac{p}{5} = 23$

Multiply 5 to both sides just like you did with 9.

$\sf \dfrac{p}{5} \times 5 = 23 \times 5$

The 5's on the right cancel out giving us:

$\sf p = 23 \times 5$

igreen · Answer

Just multiply to get your answer.
