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.
On comparing with 
The value of x=-1.
Answer:
D) The value cannot be determined from the information given
Step-by-step explanation:
If 3x−y=12, what is the value of 8x/2y ?
We can progress till:
- 3x-y=12
- y= 3x-12
- 8x/2y= 4x/y= 4x/(3x-12),
we need the value of x to determine the result.
So the answer is the last choice
