    Step-by-step explanation:

    Step 1: Define

    Identify

    \displaystyle p(d + x) = 2x + 3

    Step 2: Solve for d

    1. [Division Property of Equality] Divide p on both sides:                                  \displaystyle d + x = \frac{2x + 3}{d}
    2. [Subtraction Property of Equality] Subtract x on both sides:                         \displaystyle d = \frac{2x + 3}{d} - x
