2. Goten77

so solve for x? meaning get x by itself?

3. mzroze

yes

4. Goten77

k so divide the entire right side by everything but the x part... and you should get this|dw:1358921885935:dw|

5. mzroze

dividr it by what

6. Azteck

$B=\frac{ 1 }{ 8 }\pi P^2x$ $8B=\pi P^2x$ $x=\frac{8B}{\pi P^2}$

7. Azteck

Multiply by 8 first to both sides.

8. Azteck

Then divide by $\pi P^2$ to both sides.

9. mzroze

how do you divide 8 by B?

10. Azteck

What do you mean divide 8 by B?

11. Azteck

I never divided 8 by B.

12. Goten77

u can just put a parenthesis around the right side but not including the x then divide that.. but depending on how much is wanted to be simplified will vary the answer.. either way it will work out some how

13. mzroze

or 8 times B I mean

14. mzroze

im totally lost, that makes absolutely no sense to me

15. Azteck

Practice with normal numbers.

16. Azteck

Let P be a number. Let B be a number and x be a number.

17. mzroze

ok, yy would you multiply anything by 8 though?
