Answer:
Step-by-step explanation:
We have

So we find GCD = 1
2) By back substitution we get
71407 (543) - 19387(2000) =1
So x = 543 and y = -19387
Because we got 71407 (543) - 19387(2000) =1
y cannot be positive
y can only be negative
Answer:
the answer is C, comment if you need explanation
Step-by-step explanation:
here is the solution.
Round the answer as needed.
You need to multiply three on both sides, add 6x to both sides, then divide by 4 on both sides. In the end, you will get y=3/2x+21/2.
