p = Pamela’s age, j = Jiris’ age
2j = p
p + j = 30
Then change things around a bit...
p + j = 30 or
30 - p = j
Then substitute
2(30 - p) = p
And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20

Answer:
33
Step-by-step explanation:
Let's call their ages m and b.
We have:
m = b + 12
m - 17 = 4(b - 17) → m = 4b - 51
b + 12 = 4b - 51
3b = 63
b = 21
m = 21 + 12 = 33
