Step-by-step explanation:
To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.
Answer:

Step-by-step explanation:
Given:
The equation given is:

We simplify the given equation using the following law of indices:

Therefore,

Since the base on both the sides is same, therefore, their exponents must also be same. This gives,

Therefore, the value of 'n' is 3.
The answer is 20.
First you would multiple the negative with the negative 12, then you just add/subtract.
Answer: 24
