The answer is -485.
To find this we first need to get rid of the 5 in the denominator.
100 =
So we multiply each side by 5.
500 = 15 - x
Now we need to get rid of the 15. So we subtract 15 from both sides.
485 = -x
Then since our x is negative, we need to divide by -1.
-485 = x

Answer:
-1 is the inverse of 16 modulo 17.
Step-by-step explanation:
To find : An inverse of 16 modulo 17 i.e. ?
Solution :
First we find the GCD of (17,16) using Euclid's algorithm,
Remainder is 1.
Which means, GCD(17,16)=1
Using back substitution we get,
i.e. -1 is the inverse of 16 modulo 17.
