Explanation:
The problem asks to find the values "b" and "c" in a way that
the solutions of the equation |x - b| = c are x= 1/2 and x= -1/3.
It means that "b" is the center of the segment [-
].
This segment has the length
Hence, the half of this length is
.
Therefore, the center of the segment is

Thus the value of "b" is found: it is b =
.
Then the value of "c" is c =
.
