Mother 13391

Mom is nine years older than her son. In 19 years, his son will be as old as his mother is now. How old is the mom, and how old is the son?

Correct answer:

m =  29
s =  10

Step-by-step explanation:


m=9+2·s
s+19 = m

m-2s = 9
m-s = 19

Row 2 - Row 1 → Row 2
m-2s = 9
s = 10


s = 10/1 = 10
m = 9+2s = 9+2 · 10 = 29

m = 29
s = 10
