Filip's 7158

Filip's friend is three times younger than Filip's father. He will be two years younger. How old is Filip's friend?

Correct answer:

k =  13
o =  39

Step-by-step explanation:


k=o/3
k+13 = (o+13)/2

3k-o = 0
2k-o = -13

Row 2 - 2/3 · Row 1 → Row 2
3k-o = 0
-0.33o = -13


o = -13/-0.33333333 = 39
k = 0+o/3 = 0+39/3 = 13

k = 13
o = 39
