To determine which of the given equations has no solutions, we can analyze each one.

  1. \(6x + 3 = -6x + 3\):

    • Rearranging gives \(6x + 6x = 3 - 3\) → \(12x = 0\) → \(x = 0\).
    • This equation has a solution.
  2. \(-6x + 4 = -6x + 3\):

    • Rearranging gives \(-6x + 6x = 3 - 4\) → \(0 = -1\).
    • This is a contradiction, indicating there are no solutions.
  3. \(-6x + 4 = 6x + 3\):

    • Rearranging gives \(-6x - 6x = 3 - 4\) → \(-12x = -1\) → \(x = \frac{1}{12}\).
    • This equation has a solution.
  4. \(6x + 4 = 6x + 4\):

    • This is an identity, true for all \(x\), so it has infinitely many solutions.

The equation that has no solutions is:

\(-6x + 4 = -6x + 3\).
