But that is also the same as 3*5 + 3*4 = 15 + 12 = 27, right?
i understand the above. but i don't understand how that process is related to what we have done with the equation.
75F - 201.5Fy = -201.5y + 111.5
F(75 - 201.5y) = -201.5y + 111.5
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.
