Find those points on x-axis each of which is at a distance of 5 units from the points A (5, -3).

We are asked to find points on the x-axis that are 5 units away from the point \( A(5, -3) \).

### Step 1: Generalize the form of points on the x-axis
Any point on the x-axis can be written as \( P(x, 0) \), since the y-coordinate of any point on the x-axis is 0.

### Step 2: Apply the distance formula
The distance \( d \) between two points \( P(x_1, y_1) \) and \( Q(x_2, y_2) \) is given by the formula:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Here, \( P(x, 0) \) is the point on the x-axis, and \( A(5, -3) \) is the given point. The distance between these points is 5 units. So, we can set up the equation as follows:
\[
\sqrt{(x - 5)^2 + (0 - (-3))^2} = 5
\]
This simplifies to:
\[
\sqrt{(x - 5)^2 + 3^2} = 5
\]
\[
\sqrt{(x - 5)^2 + 9} = 5
\]
### Step 3: Solve the equation
Square both sides to eliminate the square root:
\[
(x - 5)^2 + 9 = 25
\]
\[
(x - 5)^2 = 16
\]
Take the square root of both sides:
\[
x - 5 = \pm 4
\]
This gives two possible solutions:
1. \( x - 5 = 4 \)  ⟹  \( x = 9 \)
2. \( x - 5 = -4 \)  ⟹  \( x = 1 \)

### Step 4: Conclusion
The points on the x-axis that are 5 units away from \( A(5, -3) \) are \( (9, 0) \) and \( (1, 0) \).
