To determine which equation has the solution x = 4, we need to substitute x = 4 into each equation and see if it holds true.

Option A: 1.25x – 1.05 = 6.65

1.25 × 4 – 1.05 = 5 – 1.05 = 3.95 ≠ 6.65

This equation does not hold true.

Option B: 3.75x + 5.9 = 9.1

3.75 × 4 + 5.9 = 15 + 5.9 = 20.9 ≠ 9.1

This equation does not hold true.
