Explanation:

Step1: Combine like terms with \( x \)

We have the \( x \)-terms: \( -4x - 2x + 2x + 7x \). Let's add their coefficients: \( (-4 - 2 + 2 + 7)x \). First, calculate \( -4 - 2 = -6 \), then \( -6 + 2 = -4 \), and finally \( -4 + 7 = 3 \). So the \( x \)-terms simplify to \( 3x \).

Step2: Combine constant terms

The constant terms are: \( -8 - 9 + 7 + 2 \). Calculate step by step: \( -8 - 9 = -17 \), then \( -17 + 7 = -10 \), and finally \( -10 + 2 = -8 \).

Step3: Combine the results

Now, combine the simplified \( x \)-terms and constant terms: \( 3x - 8 \).

Answer:

\( 3x - 8 \)
