    Answer:

    x = 2

    General Formulas and Concepts:

    Pre-Algebra

    • Order of Operations: BPEMDAS
    • Equality Properties

    Step-by-step explanation:

    Step 1: Define equation

    3(x + 8) = 30

    Step 2: Solve for x

    1. Divide 3 on both sides:                              x + 8 = 10
    2. Subtract 8 on both sides:                           x = 2

    Step 3: Check

    Plug in x into the original equation to verify it is a solution.

    1. Substitute in x:                    3(2 + 8) = 30
    2. Add:                                     3(10) = 30
    3. Multiply:                               30 = 30

    Here we see that 30 does indeed equal 30.

    ∴ x = 2 is a solution of the equation.
