Answer 1

Rewriting Equations

Answer:

`y = (bfm)/(km -f)\\`

Explanation:

Solving
`ky -bf = (fy)/(m)\\` for
`y`:

`ky -bf = (fy)/(m) \\ (ky -bf) \cdot m = (fy)/(m) \cdot m \\ kym -bfm = fy \\ kym -bfm +bfm = fy +bfm \\ kym = fy +bfm \\ kym -fy = fy +bfm -fy \\ kym -fy = bfm \\ y(km -f) = bfm \\ (y(km -f))/(km -f) = (bfm)/(km -f) \\ y = (bfm)/(km -f)`
