xz_007 [3.2K]

Answer:

Pamela is 7 years younger than Jiri. The sum of their ages is 39. What is Jiri ‘s age?
astraxan [27]

Based on the task given, Pamela's age and juri's age is 16 and 23 years respectively.

<h3>Equation</h3>

  • Juri's age = x
  • Pamela's age = x - 7
  • Their total age = 39

x + (x - 7) = 39

x + x - 7 = 39

2x = 39 + 7

2x = 46

x = 46/2

x = 23

Therefore,

Juri's age = x

= 23 years

Pamela's age = x - 7

23 - 7

= 16 years
