THere are at least two ways to solve this. Here is one of them: What we have here is a circle in disguise with center (4,-3) and radius 5. Its equation is

since we want coordinates on the x-axis, set y = 0 and solve for x like this

take a square root to get
x-4 = +-5
So,
x = 9
OR
x = -1
This means that (9,0) and (-1,0) is 5 units from (4,-3)
