Question 1189623
<br>
If the sum of their ages will be 40 5 years from now, then the sum of their ages now is 30.<br>
Given that Jake is 2 years older than Rosa, we can solve the problem formally:<br>
let x = Rosa's age
then x+2=Jake's age<br>
The sum of their ages is 30:
x+x+2=30
2x+2=30
2x=28
x=14<br>
ANSWERS:
Rosa's age = x = 14
Jake's age = x+2 = 16<br>
If a formal algebraic solution is not required...<br>
The sum of their ages is 30;
If they were the same age, they would be 15 and 15;
But since the difference in their ages is 2, their ages are 14 and 16<br>
