Question 1106354
.
<pre>
From the condition, you havr these 2 equations

J + S = 16,    (1)     ("Her age is twice the sum of her two children ages";  16 = {{{32/2}}})
J - S  = 2     (2)     ("Her son Jose is two years older than her daughter Sophia.")


Add equations (1) and (2). You will get

2J = 16+2 = 18  ====>  J = {{{18/2}}} = 9.


<U>Answer</U>.  Jose is 9 years old.  Sofia is 9-2 = 7 years old.
