<span>Question:
</span>------------------------------------<span>
3n - 7 + 2n = 8n + 11
------------------------------------
Combine like terms:
</span>------------------------------------<span>
5n - 7 = 8n + 11
</span>------------------------------------<span>
subtract 8n from both sides:
</span>------------------------------------<span>
-3n - 7 = 11
</span>------------------------------------<span>
Add 7 to both sides
</span>------------------------------------<span>
-3n = 18
</span>------------------------------------
Divide by -3 on both sides:
------------------------------------
n = -6
------------------------------------
Answer: n = -6
