|x7850|7850

Explanation:

0x15700

0 and 15700 are the endpoints of an interval. Find the middle of the interval by subtracting 0 from 15700 and dividing the result by 2.

1570002=7850

Then write the inequality in terms of 7850 and 7850.

aa0aaaaaxaa15700
7850aa7850a7850

7850x78507850
or
x78507850,aaaaax78507850

Written as an absolute value, this inequality becomes

|x7850|7850
