Using the Substitution method, find the maximum value of
4x-2xy+3y subject to the constraint 4x-y=2
I can do the 1st part:
4x-y=2--->
4x-2=y
substitute this into the original equation:
4x-2x(4x-2)+3(4x-2)
Hope that right so far! but don't know where to go from there? anyone could help please?
thanks ;)
