Final answer:
The equivalent expression for -6n + 3 + 8n - 4 is 2n - 1 after combining like terms. However, this expression is not listed in the provided choices, suggesting an error in the question or the answer options.
Step-by-step explanation:
The student asked which expression is equivalent to the algebraic expression -6n + 3 + 8n - 4. To find the equivalent expression, we combine like terms by adding the coefficients of 'n' and combining the constant numbers.
Combining like terms:
- For 'n': -6n and +8n give us 2n
- For the constants: +3 and -4 give us -1
Therefore, the equivalent expression is 2n - 1. However, this option is not listed in the provided choices, indicating a possible omission or error in the question or answer choices. If this were the case, the correct choice would be labeled as 'None of the above' or a similar option, if available.
