x = 10

#### Explanation:

- we have to find, when the absolute value (ABS) is more than zero and when less

zero point for this ABS is x=-30 - then we will solve this problem for 2 intervals, one interval when ABS is possitive and one when ABS is negative

first interval:

(in this interval ABS is negative therefore we write -(x+30) instead of ABS)

second interval:

(in this interval ABS is possitive therefore we write (x+30) instead of ABS)
