# Very Basic Algebra Help (i'm Crap) watch

1. if you have:

y = 1300 + (1000 / P) and y = 2300, then

2300-1300 = 1000/p

1000 = 1000/p

What do you do from there to solve for P?

Cheers
2. Multiply both sides by p. Remember that p/p = 1.
3. Nevermind multiplying by p.

OP: Don't you know what you need to divide 1000 by to get a 1000?

You're an aggressive little person at times. They asked for algebra help, so I gave them algebra help, without patronising them. It might be obvious for this question, but it's not necessarily obvious for any other questions.
5. I appreciate the algebra help - thank-you.

I'm so bad at this. Like you said it was obvious for that question but i don't know the maths behind it for example,

how would you tackle:

3500 = 2000 + (1000/p)

1500 = 1000/p .....??

Yep thats right so far, and then you just do what you did before. Multiply right through by p.

To help you out, I've posted the working of how it works in a spoiler for you. Dont peek until you get an answer though .
Spoiler:

Multiplying both sides of the equation by p.

Cancel out the p's from the top and bottom of the fraction on the right hand side and you get:

7. sorted i think - 10/15 yeah? 2/3?
8. Cheers for all the help. Very much appreciated.
9. 3500 = 2000 + 1000/p

3500 - 2000 = 1000/p

1500 = 1000/p

1500p = 1000

Now if 1500 x p equals a thousand, then its natural to divide a thousand by 1500 to get what p is, so:

p = 1000/1500

Simplify the fraction

p = 1000(1)/1000(1.5)

Cancel the 1000s

p = 1/1.5

p = 0.66666666666666666666...
Cheers for all the help. Very much appreciated.
No problem.
