X = y + 2
( y + 2 ) + y = 6 -> 2y + 2 = 6
2y = 6-2
y = 2
X + 2 = 6
-> x = 4

Answer:
Step-by-step explanation:
Let's call the ages D for daughter and S for son.
We know that the son is twice as old as the daughter, so:
S = 2D
We also know that in 15 years, their ages add up to 100, so:
(40+15) + (S+15) + (D+15) = 100
55 + S + 15 + D + 15 = 100
85 + S + D = 100
S + D = 15
Substituting the first equation:
2D + D = 15
3D = 15
D = 5
Therefore:
S = 2D = 10
The son is 10 and the daughter is 5.
