Martin 2828

Martin was three times older than Pavol 12 years ago. Now Martin is twice as old as Pavol. How old is Martin now, and how old is Pavol?

Correct answer:

m =  48
p =  24

Step-by-step explanation:


m-12=3(p-12)
m =2p

m-12=3·(p-12)
m =2·p

m-3p = -24
m-2p = 0

Row 2 - Row 1 → Row 2
m-3p = -24
p = 24


p = 24/1 = 24
m = -24+3p = -24+3 · 24 = 48

m = 48
p = 24
