namely i don't understand how we can do/why we do the following
"we are just dividing 75F and 201.5Fy by F, and then multiplying them by it. You can see that these expressions are equal by multiplying F times both terms."
forgive my stupidity.
Lets put it in a simple perspective, because you still seem a bit confused (nhf, i know lots of ppl hate maths).
I think in english its a math term called distribution.
This is what happens:
AxB + AxC = Ax (B+C)
Or lets try an example with some real numbers.
15 + 25 = 40
15 + 25 = 3x5 + 5x5 = 5x (3+5) = 5x 8 = 40
