1 answer

To simplify the expression \( 4 + 8(3x - 2) - 7x \), we will use the order of operations and the distributive property. Let's go through the steps carefully!

Step 1: Distribute the 8

First, we will distribute the \( 8 \) in the term \( 8(3x - 2) \):

\[ 8(3x) - 8(2) \]

Calculating that gives:

\[ 24x - 16 \]

Step 2: Rewrite the expression

Now, replace \( 8(3x - 2) \) in the original expression:

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

Step 3: Combine like terms

Next, we combine all the constant terms and the terms with \( x \).

Constants:

  • \( 4 - 16 = -12 \)

Terms with \( x \):

  • \( 24x - 7x = 17x \)

Step 4: Write the simplified expression

Putting it all together gives us:

\[ 17x - 12 \]

Conclusion

So, the expression \( 4 + 8(3x - 2) - 7x \) simplified is:

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