P = 9 - 0.20 * Q

How does this become

Q = 45 - 5.0 * P?

Times both sides by 5… WHAT??? i am freaking out.

P = 9 - 0.20 * Q

How does this become

Q = 45 - 5.0 * P?

Times both sides by 5… WHAT??? i am freaking out.

5 *[P] = 5 * (9 - 0.2 * Q)

5 * P = 45 - Q

Q + 5 * P - 5 * P= 45 - Q + Q - 5 * P

Q = 45 - 5 * P

Take a deep, cleansing breath. Feel the tension flow out…

Thank you Breadmaker…

Actually… jsut as a refresher. I know for level 1 and life, you will need to rearrange formulas all the time.

Can anyone post a few examples???

THANKS!

Really? You want people to work up basic algebra examples for you? There’s got to be a million on the internet.
