Answer: 23
Explanation:
Let
�
m be Mike's age.
According to the given information, Gabrielle is
�
+
10
m+10 years old.
The sum of their ages is given by:
�
+
(
�
+
10
)
=
56
m+(m+10)=56
Combining like terms, we get:
2
�
+
10
=
56
2m+10=56
Subtracting 10 from both sides, we have:
2
�
=
46
2m=46
Dividing both sides by 2, we get:
�
=
23
m=23
So, Mike is 23 years old.
