Answer:

Reese has 10 years old.

Answer: Reese is 10 years old.

Step-by-step explanation:

Let be "m" the age of Martin and "r" tthe age of Reese and "l" the age of Lee.

Based on the information provided in the exercise, you can set up the following equations:

[tex]m=r+2[/tex]     [Equation 1]

[tex]m=l[/tex]         [Equation 2]

[tex]l=12[/tex]        [Equation 3]

Therefore, since:

[tex]m=l[/tex]

You know that:

[tex]m=12[/tex]

Now you must substitute the value of "m" into [Equation 1]:

[tex]12=r+2[/tex]

Finally, you must solve for "r" in order to find its value. This is:

[tex]12-2=r\\\\r=10[/tex]
