Math Problem Statement

Solving rational inequality solve for x-1 over 3+3 greater than 0

Solution

To solve the rational inequality:

x13+3>0\frac{x - 1}{3} + 3 > 0

Step 1: Simplify the inequality

Start by isolating the fraction by subtracting 3 from both sides:

x13>3\frac{x - 1}{3} > -3

Step 2: Eliminate the denominator

Multiply both sides of the inequality by 3 to get rid of the denominator:

x1>9x - 1 > -9

Step 3: Solve for xx

Add 1 to both sides:

x>8x > -8

Final Answer:

The solution to the inequality is:

x>8x > -8

This means that xx must be greater than 8-8.

Would you like further details or clarification? Here are some related questions:

  1. How would the inequality change if the numerator was a quadratic expression?
  2. What if the sign of the inequality was less than 00 instead of greater than 00?
  3. How can rational inequalities with variable denominators be solved?
  4. How do you solve rational inequalities involving absolute values?
  5. How do you solve compound inequalities?

Tip: Always be cautious about dividing or multiplying both sides of an inequality by a negative number—it reverses the inequality sign!
