Question

7 + 3k + 9 - 9

Explanation:

Step1: Combine constant terms

First, identify the constant terms in the expression \(7 + 3k+ 2 - 9\). The constant terms are \(7\), \(2\), and \(-9\). We add them together: \(7 + 2-9\).
\(7 + 2=9\), then \(9 - 9 = 0\).

Step2: Simplify the expression

After combining the constant terms, the expression becomes \(3k+0\), which simplifies to \(3k\) since adding zero does not change the value.

Answer:

\(3k\)
