Answer:

x=-\frac{24}{7}\\x=0

Step-by-step explanation:

1. You must clear the absolute value bars.

2. You have two cases: a positive case and a negative case.

3. First, you can solve the positive case as following:

7x+12=12\\7x=12-12\\x=0

4. Now, you must solve thie negative case as you can see below:

-(7x+12)=12\\-7x-12=12\\-7x=24\\x=-\frac{24}{7}

5. Therefore, the answer is:

x=-\frac{24}{7}\\x=0
