To simplify the expression \( 4 + 8(3x - 2) - 7x \), we will apply the order of operations, commutative and distributive properties. Here's a step-by-step breakdown:

  1. Apply the Distributive Property: First, we need to distribute \( 8 \) to each term inside the parentheses \( (3x - 2) \):

    \[ 8(3x) - 8(2) = 24x - 16 \]

    So the expression now looks like this:

    \[ 4 + (24x - 16) - 7x \]

  2. Combine Like Terms: Next, we will rewrite the expression, correctly grouping it for easier simplification:

    \[ 4 - 16 + 24x - 7x \]

    Now, we can combine the like terms. First, handle the constant terms:

    \[ 4 - 16 = -12 \]

    Next, combine the \( x \) terms:

    \[ 24x - 7x = 17x \]

  3. Final Result: Now, we can write the simplified expression by combining all the results:

    \[ -12 + 17x \]

This is typically written in standard form (with the variable term first):

\[ 17x - 12 \]

Thus, the simplified expression is:

\[ \boxed{17x - 12} \]
