m.. If I do I dont remember? 
I've done this problem before, I just lost my paper so I have to do it all over again. I think I did something like x+5=55 because I was starting with Karlas age and then when i got that I just added 3 and two to those numbers to get Luis and Maria's ages. would that work?

Its a good attempt but you need more than one variable since youve got 3 unknowns.
