1 answer

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:

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