_____
We assume you can figure out how to write only the digits of the number.
So,
Let Mercado's age be m and his daughter's age be d.
Our first equation: m = 37
Our second equation: m = 5 + 4d
Substitute 37 for m
37 = 5 + 4d
Subtract 5 from both sides
32 = 4d
Divide both sides by 4
8 = d
His daughter is 8 years old.
