hey chestnut....i agree wid ur method...but suppose i dont do wat u did..i.e. make num and denom relation and i assume r and s=1..main eqn. is satisfied since both sides are 0...also now dat d relation satisfies r+s=2..since d ques says least possible value , y cant 2 be d correct answer?

If r and s are positive integers,each greater than 1,and
if 11(s-1)=13(r-1),what is the least possible value of r+s?
