Answer:
Lindiwe is 18
Step-by-step explanation:
Lindiwe = L
Preeya = L/2
Sue = L-6
Their combined ages total 39 years
L+(L/2) + L-6 = 39
2.5L = 45
L=18
Lindiwe=18
Preeya= 9 (half of Lindiwe)
Sue = 12 (6 lessthan Lindiwe)
18+9+12 = 39

I think it’s 3 because it’s just how I think it is I’m probably not correct but I think it’s 3
23,24,and 25 because you do 3x+3=72.
72-3=69
69=3x
69 ÷3 is 23
x+1=24
x+2=25
