P = 9 - 0.20 * Q
How does this become
Q = 45 - 5.0 * P?
Times both sides by 5… WHAT??? i am freaking out.

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.
