To determine which equation has the solution x = -1, we'll substitute x = -1 into each equation and see which one results in a true statement.

Option A: 4x + 9 = 2x + 19

4 × (-1) + 9 = 2 × (-1) + 19

-4 + 9 = -2 + 19

5 ≠ 17

This equation is not true when x = -1.

Option B: 5x – 6 = 3x + 4

5 × (-1) – 6 = 3 × (-1) + 4

-5 – 6 = -3 + 4

-11 ≠ 1

This equation is not true when x = -1...
