p = 3j p + j = 64 4j = 64 j = 16

Pamela's age = 3 x Jiri's age = x 3 x + x = 64 4 x = 64 x = 64/4 =16 So , Jiri's age = 16 years old :-

start back with our two equations j+p = 68 p = 3j since p = 3j, we can replace "p" with "3j" whenever we see it j + p = j + 3j = 4j = 48 solve for j
MikeZack123
  • MikeZack123
okay so 4j = 48 ?
MikeZack123
  • MikeZack123
j= 12
