[tex]P=f/a[/tex]
If we're solving for "a", we need to isolate it onto one side of the equation. To do this, divide by f.
[tex]P/f=a[/tex]
Here's your answer!
Don't fret. It's the same as a normal equation.
Let's say we have 4x=16. You would divide by 4, right? So you'd have x=16/4, which is 4
But instead of 4, let's write a P, and instead of 16, an f. Px=f. If I'm solving for x, all I'd do is divide by P on both sides. x=f/P. See?
Going back to the original equation, P=f/a, to solve for f, you would have to multiply by a. Your answer would be Pa=f.
