Math Problem Statement

2 times the answer of x is greater than or equal to 6 and less than x. Find the range of x.

Solution

We need to solve the inequality given by the problem:

2x6 and 2x<x2x \geq 6 \text{ and } 2x < x

Step 1: Solve the first inequality 2x62x \geq 6

To solve 2x62x \geq 6:

x62=3x \geq \frac{6}{2} = 3

Step 2: Solve the second inequality 2x<x2x < x

To solve 2x<x2x < x:

2xx<0    x<02x - x < 0 \implies x < 0

Step 3: Combine the inequalities

Now, let's combine the two conditions:

  1. x3x \geq 3
  2. x<0x < 0

These two conditions cannot be true at the same time because there is no xx that satisfies x3x \geq 3 and x<0x < 0 simultaneously.

Conclusion

There is no value of xx that satisfies both inequalities. Therefore, there is no range of xx that meets the given conditions.

  1. What if the inequality was 2x>62x > 6 and 2xx2x \leq x?
  2. How would the solution change if the inequalities were combined into a single inequality?
  3. Can you provide an example where 2x<62x < 6 and x>0x > 0?
  4. How would the range of xx change if the inequalities were 2x62x \leq 6 and 2x>x2x > x?
  5. How do you solve a system of linear inequalities?

Tip: Always check if a solution satisfies all parts of a compound inequality when combining them.
