Math Problem Statement

|6-2x|>1

Solution

To solve the inequality 62x>1|6 - 2x| > 1, we proceed as follows:

Step 1: Break the absolute value inequality

For any absolute value inequality of the form A>B|A| > B, where B>0B > 0, it is equivalent to: A<BorA>BA < -B \quad \text{or} \quad A > B Here, A=62xA = 6 - 2x and B=1B = 1, so: 62x<1or62x>16 - 2x < -1 \quad \text{or} \quad 6 - 2x > 1

Step 2: Solve each inequality separately

Inequality 1: 62x<16 - 2x < -1

62x<16 - 2x < -1 2x<16-2x < -1 - 6 2x<7-2x < -7 Divide by 2-2 (remember to reverse the inequality sign): x>72x > \frac{7}{2}

Inequality 2: 62x>16 - 2x > 1

62x>16 - 2x > 1 2x>16-2x > 1 - 6 2x>5-2x > -5 Divide by 2-2 (again, reverse the inequality sign): x<52x < \frac{5}{2}

Step 3: Combine the results

The solution is: x>72orx<52x > \frac{7}{2} \quad \text{or} \quad x < \frac{5}{2}

In interval notation, this is: (,52)(72,)(-\infty, \frac{5}{2}) \cup (\frac{7}{2}, \infty)

Final Answer:

x(,52)(72,)x \in (-\infty, \frac{5}{2}) \cup (\frac{7}{2}, \infty)
