Joel is twice as old as kayla in 5 years the sum of their ages will be 55 years what are the ages of two people

Kayla is 15 while joel is 30

Let J represent Joel
Let K represent Kayla
Joel is twice as old as Kayla
J = 2K
In five years time, the sum of their ages is 55
(J + 5) + (K + 5) = 55
J + K + 10 = 55
J + K = 45
substitute J = 2K
2K + K = 45
3K = 45
K = 15
and J =2K
J = 2 * 15=30
Joel is 30 years old
Kayla is 15 years old
pls mark as brainliest
