Math Problem Statement
Solution
The problem in the image is asking to solve the absolute value inequality:
Step 1: Remove the fraction
To eliminate the fraction, multiply both sides of the inequality by 7:
Step 2: Solve the absolute value inequality
The general rule for solving inequalities of the form is that:
In this case, and . So, we split the inequality into two cases:
Step 3: Solve each inequality
Final Answer:
The solution to the inequality is:
Thus, the answer is:
- and .
