Step-by-step explanation:
If x is even, then we know that x = 2k for a k ≥1
If y is odd, then we know that y = 2j -1 for a j≥1
Therefore, x + y can be written similarly as:
And clearly, 2(k + j) -1 is odd.
Therefore, the sum x + y is an odd number.

Answer:
<h3>A. y=-2x+3z+25</h3>Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<u>To solve:</u>
- The value of y.
<u>First, you have to subtract by 2x-3z from both sides.</u>
<u>Solve.</u>
- <u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>
