answer the following, The choices are even / odd

Write a proof by contradiction of the following.
Let x and y be integers. If x and y satisfy the equation
3x + 5y = 159
then at least one of x and y is odd.
Let x and y be integers that satisfy the equation 3x + 5y = 159. Suppose, to the contrary, that both x and y are even. Then x =
y =
159 = 2
for some integer k₂. Then 159 = 3x + 5y =
+ 1 is also ---Select---
This contradicts Axiom 1.2.
=
for some integer k₁ and
(3k₁ + 5k₂) is ---Select--- . But
