1) How do we get to the first key step in solving any function involving absolute value equations? |
2) How do we solve absolute value equations? |
Answer: |
1) We isolate everything inside of the absolute value signs. |
2) We create two equations based on whether the expression inside the absolute value is positive or negative. |
Then we solve both equations. |
Solution:
ExpandStep 1: |
---|
Isolate the absolute values. First by adding 7 to both sides, then dividing both sides by 2. |
This leads to |

Now we create two equations: |
ExpandStep 3: |
---|
Now we solve both equations. The first leads to the solution |
