Math Problem Statement

2(x − 3) < 8

Solution

To solve the inequality 2(x3)<82(x - 3) < 8, follow these steps:

Step 1: Expand the inequality

Distribute the 22 to terms inside the parentheses: 2x6<82x - 6 < 8

Step 2: Isolate the variable term

Add 66 to both sides to eliminate the constant term on the left-hand side: 2x<142x < 14

Step 3: Solve for xx

Divide both sides by 22 to isolate xx: x<7x < 7

Final Solution:

x<7x < 7

This means the solution set includes all values of xx less than 77.

  1. How would the solution change if the inequality were 2(x3)82(x - 3) \leq 8?
  2. Can you represent this inequality solution on a number line?
  3. How do you solve inequalities with fractions, e.g., 13(x6)<2\frac{1}{3}(x - 6) < 2?
  4. What happens if the inequality sign is flipped, e.g., 2(x3)>82(x - 3) > 8?
  5. How does solving inequalities differ from solving equations?

Tip: When multiplying or dividing inequalities by a negative number, remember to flip the inequality sign!
