Analysis
To solve the inequality |3c - 4| < 12, we can break it down into two cases based on the absolute value expression.
Case 1: 3c - 4 ≥ 0 (when the absolute value is positive or zero)
In this case, the inequality becomes 3c - 4 < 12. Adding 4 to both
sides of the inequality gives 3c < 16. Dividing both sides by 3
(since 3 is positive) gives c < , which is
approximately 5.33.
Case 2: 3c - 4 < 0 (when the absolute value is negative)
In this case, the inequality becomes -(3c - 4) < 12. Simplifying the
inequality gives -3c + 4 < 12. Subtracting 4 from both sides of the
inequality gives -3c < 8. Dividing both sides by -3 (since -3 is
negative) reverses the inequality sign, giving c > ,
which is approximately -2.67.
Combining the results from the two cases, we have < c
