Answer:
z = 2
Explanation:
The | | represents absolute value which means the number's distance from 0. Any number's absolute value is going to be a positive number.
So, 5 + what number plus 3 gives you 10?
10 - 3 = 7 and 7 - 5 = 2.
So, |5 + 2| + 3 = 10.
The distance from 5 and 0 is 5
Distance from 2 and 0 is 2
