Question 1048501: I'm not even sure if this is the right topic, but here's my problem.
The lengths of the sides of a rectangle are all integers. Four times its perimeter is numerically equal to one less than its area. Find the largest possible perimeter of such a rectangle.
Now I tried manipulating the variables but I'm stuck here.
8x+8y+1=xy
I don't know how to relate this with the maximum value or solve x and y independently or like that, so I really need help.
Thanks.
