Answer: Brody's Age is 19 and Trinity's age is 11

Step-by-step explanation:

x = Trinity's age

2x-3= Brody's age

The sum of the ages is 30, so

x + (2x-3) = 30

3x - 3 = 30

add 3 to both sides 30 turns into 33 so,

3x = 33

divide by 3 both sides

x = 11 which is trinity's age and plug x  into 2x - 3 which is 19 so that's Brody's age.
