System of equations
Post Body
Can someone please explain to me the process of solving a system such as this one?
xy = 500
(x-5)(y-8)=240
Where x and y are positive numbers.
I have developed the second equation, which got me 5x 8y=300. I have no idea where to go from there.
Should I use the substitution method, or is there a better, faster way?
Thanks in advance
