The Attempt at a Solution
Well guys, this is a problem I've been having for the last 2 days and with my midterm tomorrow I have no time to fiddle around with it.
So, I do not understand how (where it says b) how
Im going to use a division symbol ( / ) for indicating a break in the line.
(3x+5y)[1 / -2] + (4x+7y)[-1 / 1] is equal to [-x-2y / -2x-3y]
I have no understanding of this, because if you think of [x / y] which means it should be [(3(1) + 5(-2)) / (4(-1) + 7(1))]
which is equal to [3x-10y / -4x+7y] which is not equal what the answer is.
I hope you understand what I am asking and need a response asap, thanks in advance!
