Final answer:
To find RR's age, an algebraic equation is set up with RR being x years old and Qe being x - 16 years old. Solving 2x - 16 = 30 yields RR's age as 23 years old. Hence, RR is 23 years old.
Step-by-step explanation:
The question given is a simple algebra problem where we need to find out the age of RR knowing that Qe is 16 years younger than RR and the sum of their ages is 30. To solve this, let's use variables: let's say RR's age is x years. Therefore, Qe's age will be x - 16 years. Given that together their ages sum up to 30 years, we can write the equation as:Now, substitute the expression for QE from the first equation into the second equation:
x + (x - 16) = 30
Solving for x:
2x - 16 = 30
2x = 30 + 16
2x = 46
x = 46 / 2
x = 23
Hence, RR is 23 years old.
