Can someone help me out solved this problem plz! I need help ASAP! Help me I will mark you as brainiest! Show steps!

Answer:
Kendra: 14, Marrisa: 15
Step-by-step explanation:
Sorry it was a bit late.
What you know:
The two girl's ages combined is 29.
Kendra is younger.
For these problems, I just kind of like to do it in my head, so the thought process is a bit odd. I feel like this is the easiest way I can explain.
Add one to the number (if it's odd, make it even I guess)
29+1=30
Divide by 2
30/2=15
this is the age of the older.
Subtract 1, this is the age of the younger.
If this didn't make sense, sorry, but the answer is correct :P
