Question

simplify the expression: n + 4.5 - 0.3n - 3

Explanation:

Step1: Combine like terms for n

We have \( n - 0.3n \). Since \( n = 1n \), we subtract the coefficients: \( 1 - 0.3 = 0.7 \), so \( n - 0.3n = 0.7n \).

Step2: Combine constant terms

We have \( 4.5 - 3 \). Subtracting these gives \( 1.5 \).

Step3: Combine the results

Putting the two parts together, we get \( 0.7n + 1.5 \).

Answer:

\( 0.7n + 1.5 \)
