Absolute Inequalities F0Ced7
1. **State the problem:** Solve the system of inequalities:
$$|3x - 2| < 7$$
$$|x - 1| \geq 2$$
2. **Recall the definition of absolute value inequalities:**
- For $|A| < B$, where $B > 0$, the solution is $-B < A < B$.
- For $|A| \geq B$, where $B > 0$, the solution is $A \leq -B$ or $A \geq B$.
3. **Solve the first inequality:**
$$|3x - 2| < 7 \implies -7 < 3x - 2 < 7$$
Add 2 to all parts:
$$-7 + 2 < 3x < 7 + 2$$
$$-5 < 3x < 9$$
Divide all parts by 3:
$$-\frac{5}{3} < x < 3$$
4. **Solve the second inequality:**
$$|x - 1| \geq 2 \implies x - 1 \leq -2 \text{ or } x - 1 \geq 2$$
Solve each:
$$x \leq -1 \text{ or } x \geq 3$$
5. **Find the intersection of the two solution sets:**
From the first inequality: $-\frac{5}{3} < x < 3$
From the second inequality: $x \leq -1$ or $x \geq 3$
The intersection is where both inequalities hold simultaneously:
- For $x \leq -1$ and $-\frac{5}{3} < x < 3$, the overlap is $-\frac{5}{3} < x \leq -1$
- For $x \geq 3$ and $-\frac{5}{3} < x < 3$, there is no overlap because $x$ cannot be both $\geq 3$ and $< 3$
6. **Final solution:**
$$-\frac{5}{3} < x \leq -1$$
