Answer:
Ayitey is 10 years old
Naa is 13 years old
Explanation:
We can find Naa and Ayitey's ages using a system of equaions where N represents Naa's age and A represents Ayitey's age.
First equation:
Since the sum of their ages is 23, our first equation is given by:
N + A = 23
Second equation:
Since Naa is 3 years older than Ayitey, our second equation is given by:
N = A + 3
Method to solve: Substitution:
We can first solve for A by substituting N = A + 3 for N in N + A = 23:
A + 3 + A = 23
(2A + 3 = 23) - 3
(2A = 20) / 2
A = 10
Thus, Ayitey is 10 years old.
Determine Naa's age by plugging in 10 for A in any of the two equations in our system:
- We can find Naa's age by plugging in 10 for A in any of the two equations in our system.
Let's use the second equation:
N = 10 + 3
N = 13
Thus, Naa is 13 years old.
