Is y=y+8 even, odd, or neither
SIZIF [17.4K]

The expression y = y + 8 does neither represent an odd number nor an even number.

<h3>Does represent a given equation an even or odd number or neither?</h3>

In this problem we must check if a given algebraic equation represents an even number or an odd number or neither by using algebraic means. Even numbers are integers, whose last digit is 0, 2, 4, 6 or 8, whereas odd numbers are integers, whose last digit is 1, 3, 5, 7 or 9. Now we proceed to  check the expression:

y = y + 8                     Given

y + (- y) = 8                 Compatibility with addition / Existence of additive inverse / Modulative property

0 = 8                           Existence of additive inverse / Modulative property / Result

The expression y = y + 8 does neither represent an odd number nor an even number.
