Answer: The son is 30 and the mother is 60
Step-by-step explanation:
Mother's age = m
Son's age = s
m = s + 30
m-15 = 3(s - 15)
m - 15 = 3s - 45
m = 3s - 30
(Substitution)
s + 30 = 3s - 30
2s = 60
s = 30
m = 60

Step-by-step explanation:
||x-5|+2|≤3
-3 ≤ (|x-5| +2) ≤ 3
-5 ≤ |x-5| ≤ 1
|x-5| ≥ -5 => not required
