Question 1048501
x and y are expected to be integers (or better, whole numbers).
{{{4(2x+2y)=xy-1}}}----------the description.


The perimeter, as a function may be {{{highlight_green(p=2x+2y)}}}, and you would want to be able to substitute for either x or for y.


Look again at the equation formed from the description.
{{{8x+8y=xy-1}}}
{{{8x+8y-xy=-1}}}
{{{8y-xy=-1-8x}}}
{{{y(8-x)=-1-8x}}}
{{{y=(-8x-1)/(8-x)}}}
{{{y=((-8x-1)/(8-x))((-1)/(-1))}}}------multiplying by 1 to produce more convenient formula,
{{{highlight_green(y=(8x-1)/(x-8))}}}



I leave the rest of this problem unfinished so that you could continue and finish.
