sir in the first (finite no. of solutions) method what we do if y also have a coefficient ?

Hi Kumkum. In that case the 'y' coefficient will also be sent to the RHS. It will become the denominator there. And you'll have to take values of x while ensuring that 'y' still gets integral values.
In the third example, 5x would be greater than 100 upto infinity. Thus x wud be greater than 20 and not greater than equal to 20...

Hey Ayush, you're right. This has been pointed out by Abhishek as well in the comments. Other learners kindly take note of this point. Thanks Ayush. 🙂
Good evening sir. In the second question u checked the multiple of 7 but in first question u simply took the subject y and find out the solutions. In exam how can we know as to which method to apply

@prabhu if u look below in the same slide..u wud find that he has taken y as the subject n explained as to y der wud be no solutions... He has explained it both the ways either we take x as the subject or y...
Thank you finally I am able to understand maths .
