Hey there!
“Simplify 2(7n + 5m – 3m)”
2(7n + 5m – 3m)
FIRST you have to DISTRIBUTE
2(7n) + 2(5m) + 2(–3m)
2(7n) = 14n
2(5m) = 10m
2(–3m) = –6m
14n + 10m – 6m
SECOND COMBINE your LIKE TERMS
(14n) + (10m – 6m)
(10m – 6m) = 4m ⬅️ FRONT number
(14n) = 14n ⬅️ BACK number
Answer: 4m + 14n ☑️
Good luck on your assignment and enjoy your day!
