To determine which equation has the solution x = 7, we need to substitute x = 7 into each equation and see if it holds true.

Option A: 0.25x – 1.75 = 5.75

0.25 × 7 – 1.75 = 1.75 – 1.75 = 0 ≠ 5.75

This equation does not hold true.

Option B: 0.35x + 3.55 = 6

0.35 × 7 + 3.55 = 2.45 + 3.55 = 6

This equation holds true.
