Question

12 simplify the expression: $8m + 2n + m - 5m$

Explanation:

Step1: Combine like terms for \( m \)

We have \( 8m + m - 5m \). First, add \( 8m \) and \( m \): \( 8m + m = 9m \). Then subtract \( 5m \) from \( 9m \): \( 9m - 5m = 4m \).

Step2: Keep the term with \( n \)

The term \( 2n \) has no like terms to combine with, so it remains as is.

Step3: Combine the results

Putting the simplified terms together, we get \( 4m + 2n \).

Answer:

\( 4m + 2n \)
