Step-by-step explanation:
(4x-3y) ((x-1)/2y)
multiply (4x-3y) with (x-1)
you will get
4x^2-4x-3xy+3y
now dividing the whole term by 2y as at first (x-1) is divided by 2y
you get
(4x^2-4x-3xy+3y)/2y
taking common
(4x(x-1)-3y(x-1))/2y
((x-1)(4x-3y))/2y
it is your answer if you question is wrong cause you wrote x-1/2y and I did it ((x-1)/2y) so have a check if the question you wrote is wrong!
