Math Problem Statement

Solve the following absolute value inequality:

open vertical bar 2 x minus 6 close vertical bar less than 4

Solution

We are tasked with solving the absolute value inequality:

2x6<4|2x - 6| < 4

Step 1: Remove the absolute value

The inequality A<B|A| < B (where B>0B > 0) implies two conditions:

B<A<B- B < A < B

Here, A=2x6A = 2x - 6 and B=4B = 4, so we can write:

4<2x6<4-4 < 2x - 6 < 4

Step 2: Solve the compound inequality

Now we solve the inequality 4<2x6<4-4 < 2x - 6 < 4 by isolating xx.

First, solve the left side of the inequality:

4<2x6-4 < 2x - 6

Add 6 to both sides:

4+6<2x-4 + 6 < 2x

2<2x2 < 2x

Now divide by 2:

1<x1 < x

So, x>1x > 1.

Next, solve the right side of the inequality:

2x6<42x - 6 < 4

Add 6 to both sides:

2x<102x < 10

Now divide by 2:

x<5x < 5

Step 3: Combine the results

From the two parts, we have:

1<x<51 < x < 5

Final Answer:

The solution to the inequality 2x6<4|2x - 6| < 4 is:

x(1,5)x \in (1, 5)

  1. How can you solve an absolute value inequality when the right-hand side is negative?
  2. What happens if the inequality is 2x64|2x - 6| \leq 4 instead of 2x6<4|2x - 6| < 4?
  3. How can you solve absolute value equations?
  4. What are the steps for solving a compound inequality?
  5. How would you graph the solution x(1,5)x \in (1, 5) on a number line?

Tip: Always remember that absolute value inequalities can often be rewritten as compound inequalities, making them easier to solve step-by-step!
