Question

simplify the expression:
10 + 4z - 4 - 4

Explanation:

Step1: Combine constant terms

First, we handle the constant terms (the terms without the variable \( z \)). The constant terms are \( 10 \), \( -4 \), and \( -4 \). So we calculate \( 10 - 4 - 4 \).
\( 10 - 4 = 6 \), then \( 6 - 4 = 2 \).

Step2: Rewrite the expression

Now we rewrite the original expression with the simplified constant term. The term with the variable \( 4z \) remains unchanged. So the simplified expression is \( 2 + 4z \) (or we can also write it as \( 4z + 2 \) since addition is commutative).

Answer:

\( 4z + 2 \) (or \( 2 + 4z \))
