<u>Algebra I</u>

Terms

Step-by-step explanation:

<u>Step 1: Define</u>

(4m + 7n - 6p) - (2m - 3n - 4p)

<u>Step 2: Simplify</u>

Distribute negative: 4m + 7n - 6p - 2m + 3n + 4p
Combine like terms (m): 2m + 7n - 6p + 3n + 4p
Combine like terms (n): 2m + 10n - 6p + 4p
Combine like terms (p): 2m + 10n - 2p
