Also I observed that for the question with solution (5,3); If we put y = 0 in 12x = 17y +9; we get x = 9/12 , remainder of which is 3, and 3 is the value that we get for y. Is this a valid shortcut?

The last question x and y also take value of 8&3 respectively. Then the answer bcms 17 . It also applies the same rules.. But different answers . Also instead of trial and error if v follow the second method v might end up with different answers also. How do v know which is the correct answer. Please respond to this queries. Thanks in advance 😊

[@DevendraSingh-qn5qf]

In which question u r splitting denominator as 8&3

[@elcucuy2236]

we have to find the least values of x and y

[@vamshicatprep9441]

Yeah we get 17 but 17/10 remainder is 7 again.

[@rumourtales4997]

remainder should be always less than the denominator.If remainder is greater than denominator then we have to divide it again. thus we divide 17 again by 10 as 17 > 10 .

At 4:10 in the video, why we have divided -1x by 9 because in the previous step we have already found the remainder to the expression of (17x -9y)/9, so while finding remainder hadn't it been cancelled in the first step? My question is why we are writing (-1x)/9 ?

we are finding the value of numerator for which , when divided by denominator we get the remainder as 1. the coefficient of x can vary depending on the problem. Hope it clarifies.

why we have not applied euler when dividing 97 by 2 but we have applied euler when dividing 97 by 5, in this also we can get reminder of 2 directly then ?

[@082_amimorakhia3]

The ans we get is 64 only because 7x+1 = 7(9) + 1 = 63+1 = 64 and 13y+12 = 13(4) + 12 = 52+12 = 64

Great videos sir, thank you One query: @5.12 i didn't understand the answer to the question 'at what value of x we will get the remainder as 1 '. Please explain. thank you

[@anilbhai1652]

I also confused first time, but don't worry. First of all always transfer the -ve sign to right, now you have to find a value of X which when dividing by 9 gives you -1 as a remainder. Since remainder never be negative, convert -1 to +ve form which is 8 ( since 9= 8+1 we have always two remainder). Now the right side value is always the answer probably! Hence X = 8 is the answer because if you divide 8 by 9 then remainder will be 8.
