    Yes

    Step-by-step explanation:

    To solve, evaluate each equation when x = 4.

    Multiply: 4 (2 + 12)

    Add: 4 (14)

    Multiply: 56

    Final answer: 56

    Then,

    Rewrite: 8 + 12 (4)

    Multiply: 8 + 48

    Add: 56

    Final answer: 56

    Yes, both equations are equivalent.
