Question

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 \(n\), which are \(-4.4n\) and \(-2n\). Using the rule of combining like terms \(ax+bx=(a + b)x\), we have \(-4.4n-2n=(-4.4-2)n=-6.4n\).

Step3: Form 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 \(-6.4n + 9.8\))
