Answer

x>−135x > -\frac{13}{5}

Step-by-step solution

8 steps
  1. Simplify the first term and find the Least Common Multiple (LCM) of the denominators.

    The inequality is:

    6x3−5x−34−2x−16>−16\frac{6x}{3} - \frac{5x-3}{4} - \frac{2x-1}{6} > -\frac{1}{6}

    Simplify the first term: 6x3=2x\frac{6x}{3} = 2x.
    The denominators are 3, 4, 6, and 6. The LCM of 3, 4, and 6 is 12.

  2. Multiply every term in the inequality by the LCM (12) to eliminate the denominators.

    12(2x)−12(5x−34)−12(2x−16)>12(−16)12 \left( 2x \right) - 12 \left( \frac{5x-3}{4} \right) - 12 \left( \frac{2x-1}{6} \right) > 12 \left( -\frac{1}{6} \right)
  3. Simplify each term.

    24x−3(5x−3)−2(2x−1)>−224x - 3(5x-3) - 2(2x-1) > -2
  4. Distribute the numbers into the parentheses.

    Remember to distribute the negative signs.

    24x−(15x−9)−(4x−2)>−224x - (15x - 9) - (4x - 2) > -2 24x−15x+9−4x+2>−224x - 15x + 9 - 4x + 2 > -2
  5. Combine like terms on the left side of the inequality.

    (24x−15x−4x)+(9+2)>−2(24x - 15x - 4x) + (9 + 2) > -2 5x+11>−25x + 11 > -2
  6. Subtract 11 from both sides of the inequality.

    5x>−2−115x > -2 - 11 5x>−135x > -13
  7. Divide both sides by 5 to solve for xx.

    x>−135x > -\frac{13}{5}

    As a decimal, x>−2.6x > -2.6.

  8. Represent the solution on a number line.

    Draw a number line. Place an open circle at −2.6-2.6 (since xx is strictly greater than −2.6-2.6, not equal to it). Draw an arrow extending to the right from the open circle, indicating all values greater than −2.6-2.6.

    The solution is x>−135\boxed{x > -\frac{13}{5}}.

        A[Number Line] --> B(--- -3 --- -2.6 --- -2 --- -1 --- 0 ---);
        B --> C{Open circle at -2.6};
        C --> D[Arrow pointing right from -2.6];
