Question

8 simplify the expression: 2.8 - 4.4n - 2n + 7

Explanation:

Step1: Combine constant terms

Add the constant terms \(2.8\) and \(7\). So, \(2.8 + 7 = 9.8\).

Step2: Combine like - variable terms

Combine the terms with \(n\): \(-4.4n-2n=(-4.4 - 2)n=-6.4n\).

Step3: Write the simplified expression

Combine the results from step 1 and step 2. The simplified expression is \(9.8-6.4n\) (or we can also write it as \(-6.4n + 9.8\)).

Answer:

\(9.8 - 6.4n\) (or \(-6.4n+9.8\))
