To simplify the expression \( 4 + 8(3x - 2) - 7x \), we will follow the order of operations and apply the distributive property.
Step 1: Apply the Distributive Property
First, we need to distribute \( 8 \) to both terms inside the parentheses \( (3x - 2) \).
\[ 8(3x - 2) = 8 \cdot 3x + 8 \cdot (-2) = 24x - 16 \]
Step 2: Substitute Back into the Expression
Now we can substitute \( 24x - 16 \) back into the original expression:
\[ 4 + 24x - 16 - 7x \]
Step 3: Combine Like Terms
Now, we will combine the constant terms and the coefficients of \( x \).
First, combine the constant terms:
\[ 4 - 16 = -12 \]
Next, combine the \( x \)-terms:
\[ 24x - 7x = 17x \]
Final Expression
Now we can rewrite the simplified expression by putting it all together:
\[ 17x - 12 \]
Thus, the simplified expression for \( 4 + 8(3x - 2) - 7x \) is:
\[ \boxed{17x - 12} \]
