Hint for Section 3.9 Question 2

2. First apply the Euclidean Algorithm to 105 and 56 to find gcd(105, 56).

105

=

56 · 1 + 49
56 = 49 · 1 + 7
49 = 7 · 7 + 0

Thus, gcd(105, 56) = 7. Does a solution exist to the linear Diophantine equation 105m + 56n = -14?

If no solution exists then you are finished the question.
If a solution does exist, then work backwards through the equations of the Euclidean Algorithm to find a solution.
