To determine which equation has infinite solutions, we need to examine each option. An equation has infinite solutions if it simplifies to an identity (e.g., a statement that is always true).

  1. Equation: \(-10x + 4 = 10x + 3\)

    • Rearranging gives: \(-20x + 4 = 3\)
    • This simplifies to \( -20x = -1\) or \( x = \frac{1}{20}\). (One unique solution)
  2. Equation: \(10x + 3 = -10x + 3\)

    • Rearranging gives: \(20x = 0\)
    • This simplifies to \( x = 0\). (One unique solution)
  3. Equation: \(-10x + 4 = -10x + 4\)

    • This is an identity because both sides are always equal for any value of \(x\). (Infinite solutions)
  4. Equation: \(10x + 4 = 10x - 4\)

    • Rearranging gives: \(4 = -4\), which is false. (No solutions)

From the above analysis, the equation that has infinite solutions is:

\(-10x + 4 = -10x + 4\).
