Final answer:
The value of the expression y + 10 - 8 cannot be determined without knowing the value of y. The provided information is not relevant to this arithmetic expression.
Step-by-step explanation:
The question asks for the value of the expression y + 10 - 8. This expression involves simple arithmetic operations, specifically addition and subtraction. Unfortunately, to provide the exact numerical value, the value of y would be necessary. Since the value of y is not provided in the question, we cannot determine which of the options (A, B, C, or D) is correct. Furthermore, the additional information given does not pertain to solving this expression. Therefore, it's not possible to provide a definite answer to what the value of y + 10 - 8 is without knowing the value of y.
