Answer:
The age of the middle brother is 21.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that their ages is x, y and z.
The sum of the ages of the three Romano Brothers is 63:
This means that:
x + y + z = 63
Their ages can be represented as consecutive integers
So y = x + 1, z = y + 1 = x + 1 + 1 = x + 2
x + y + z = 63
x + x + 1 + x + 2 = 63
3x + 3 = 63
3x = 60
x = 60/3
x = 20
x is the youngest
Middle: y = x + 1 = 20 + 1 = 21
The age of the middle brother is 21.
