I have written the correct question.This is from S chand sample papers. Is there any other way to prove m=l, so that we can prove mx=ly If the distance of P(x,y) from A(l+m, l-m) and B (l-m, l+m) are equal, prove that mx=ly

We have checked our solution. It seems fine.
We have also understood how to obtain mx=ly.
You need to change the x-coordinate of the point B, which should be m-l and NOT l-m.
For this problem, you will surely get x = y only.
You can refer to the following link for this question too. It has appeared in CBSE 2016 board paper.
The solution is there too, and you will see that ,
the point B, which should be m-l and NOT l-m.
It is similar to Question Number 13.
If the point P(x, y) is equidistant from the points A(a + b, b – a) and B(a – b, a + b). Prove that bx = ay.
Only in place of a they took m and in place of b they took l.
