Step-by-Step Solution

To solve the given equation, follow these steps:

  • Step 1: Distribute the fractions
    For the left side: 12(x14)=12x+18-\frac{1}{2}(x-\frac{1}{4}) = -\frac{1}{2}x + \frac{1}{8}.
    For the right side: 12(3x)=3212x\frac{1}{2}(3-x) = \frac{3}{2} - \frac{1}{2}x.
  • Step 2: Set the distributed expressions equal to each other
    Equation: 12x+18=3212x-\frac{1}{2}x + \frac{1}{8} = \frac{3}{2} - \frac{1}{2}x.
  • Step 3: Simplify and solve for xx
    Notice that the 12x-\frac{1}{2}x terms cancel each other on both sides of the equation:
    18=32\frac{1}{8} = \frac{3}{2}.
    This clearly is not possible since 18\frac{1}{8} is not equal to 32\frac{3}{2}.
  • Conclusion: Determine if a solution exists
    The result indicates a contradiction because both sides of the equation cannot be equal. This implies that no value of xx will satisfy the equation.

Therefore, the solution to the problem is that there is no solution.

Answer

There is no solution.
