<span>Question:

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

The answer should be A. a decrease in the availability of food resources, and C. conditions that limit the availability of shelter resources, if there are two correct answer choices.
The theorem would be: If in a triangle two angles equal one another, then the sides opposite the equal angles also equal one another.
This works for any triangle in fact, not just an isosceles (obviously, the theorem implies that the triangle in question is isosceles but you don’t need to know that in advance)
