To determine which equation has the solution x = -1, we need to substitute x = -1 into each equation and see if it holds true.

Option A: 2.25x – 0.35 = -2.6

2.25 × (-1) – 0.35 = -2.25 – 0.35 = -2.6

This equation holds true.

Option B: 7.5x + 4.5 = 3

7.5 × (-1) + 4.5 = -7.5 + 4.5 = -3 ≠ 3

This equation does not hold true.
