    Answer:

    D) x = e – 1

    General Formulas and Concepts:

    Pre-Algebra

    • Equality Properties

    Algebra II

    • Natural Logarithms ln and Euler’s number e
    • Solving logarithmic equations

    Step-by-step explanation:

    Step 1: Define

    Identify

    \displaystyle ln(x + 1) = 1

    Step 2: Solve for x

    1. [Equality Property] e both sides:                                                                     \displaystyle e^{ln(x + 1)} = e^1
    2. Simplify:                                                                                                             \displaystyle x + 1 = e^1
    3. [Equality Property] Isolate x:                                                                            \displaystyle x = e - 1
