Step-by-Step Solution

To solve this problem, let's break down the equation step-by-step:

Start with the original equation:

311812x+13x=12+242224x \frac{3}{11} - \frac{8}{12}x + \frac{1}{3}x = \frac{1}{2} + \frac{2}{4} - \frac{22}{24}x

Step 1: Simplify the fractions where possible.

  • 812=23 \frac{8}{12} = \frac{2}{3} : Simplifying 812x\frac{8}{12}x gives us:23x -\frac{2}{3}x
  • 24=12 \frac{2}{4} = \frac{1}{2}
  • 2224 \frac{22}{24} simplifies to 1112 \frac{11}{12} : So, 2224x-\frac{22}{24}x becomes 1112x-\frac{11}{12}x

The equation now looks like this:

31123x+13x=12+121112x \frac{3}{11} - \frac{2}{3}x + \frac{1}{3}x = \frac{1}{2} + \frac{1}{2} - \frac{11}{12}x

Step 2: Combine like terms.

  • 23x+13x=13x-\frac{2}{3}x + \frac{1}{3}x = -\frac{1}{3}x
  • 12+12=1\frac{1}{2} + \frac{1}{2} = 1

So, the equation simplifies to:

31113x=11112x \frac{3}{11} - \frac{1}{3}x = 1 - \frac{11}{12}x

Step 3: Move all terms involving x x to one side:

Add 13x\frac{1}{3}x to both sides:

311=11112x+13x \frac{3}{11} = 1 - \frac{11}{12}x + \frac{1}{3}x

Combine the terms with x x :

  • 1112x+13x=1112x+412x=712x-\frac{11}{12}x + \frac{1}{3}x = -\frac{11}{12}x + \frac{4}{12}x = -\frac{7}{12}x

Thus, the equation is:

311=1712x \frac{3}{11} = 1 - \frac{7}{12}x

Step 4: Isolate x x :

Subtract 1 from both sides:

3111=712x \frac{3}{11} - 1 = -\frac{7}{12}x

Convert 1-1 to a fraction with a common denominator to the left side:3111111=31111=811 \frac{3}{11} - \frac{11}{11} = \frac{3 - 11}{11} = -\frac{8}{11}

Now the equation is:

811=712x -\frac{8}{11} = -\frac{7}{12}x

Multiply both sides by the reciprocal of 712-\frac{7}{12} to solve for x x :

x=811127=812117=9677 x = -\frac{8}{11} \cdot -\frac{12}{7} = \frac{8 \cdot 12}{11 \cdot 7} = \frac{96}{77}

Thus, the solution to the equation is 9677\boxed{\frac{96}{77}}.

Answer

9677 \frac{96}{77}
