Final answer:

To determine which equation has no solution, we need to solve each equation and see if there is a value of x that satisfies the equation. None of the given equations have no solution, as they all have values of x that satisfy the equations.

Step-by-step explanation:

To determine which equation has no solution, we need to solve each equation and see if there is a value of x that satisfies the equation. Let's go through each option:

1) |–x – 3| - 4 = 1:

Remove the absolute value: -x - 3 - 4 = 1

-x - 7 = 1

-x = 8

x = -8

Therefore, this equation has a solution, x = -8.

2) |2x – 1| + 9 = 9:

Remove the absolute value: 2x - 1 + 9 = 9

2x + 8 = 9

2x = 1

x = 1/2

Therefore, this equation has a solution, x = 1/2.

3) |-x + 9| - 6 = -6:

Remove the absolute value: -x + 9 - 6 = -6

-x + 3 = -6

-x = -9

x = 9

Therefore, this equation has a solution, x = 9.

4) |5 – 3x| + 7 = -1:

Remove the absolute value: 5 - 3x + 7 = -1

-3x + 12 = -1

-3x = -13

x = 13/3

Therefore, this equation has a solution, x = 13/3.

None of the given equations have no solution, as they all have values of x that satisfy the equations.
