what is the expression 4+8(3x-2)-7x when simplified? apply the order of operations and the commuitve and distributive properties show all your work.

1 answer

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

  1. Distributive Property: First, we need to apply the distributive property to the term \( 8(3x - 2) \): \[ 8(3x - 2) = 8 \cdot 3x - 8 \cdot 2 = 24x - 16 \]

  2. Substituting Back into the Expression: Now we can substitute \( 24x - 16 \) back into the original expression: \[ 4 + (24x - 16) - 7x \]

  3. Combining Like Terms: Next, combine the constant terms and the variable terms:

    • First, combine the constants: \( 4 - 16 = -12 \)
    • Then combine the \( x \) terms: \( 24x - 7x = 17x \)
  4. Final Expression: Putting it all together, we get: \[ 17x - 12 \]

So, the simplified expression is: \[ \boxed{17x - 12} \]
