Answer:
Jiri is 12 years old
Step-by-step explanation:
To start off we need to make an equation. Since we know both of their ages add up to 48 and that Pamela's age is 3 times Jiri's age we can say x(Jiri's Age) + 3x(Pamela's age) =48 --> x+3x=48
Now we have the equation x+3x=48, and we need to solve it.
First combine like terms
4x=48
Now divide both sides by 4
x=12
And now since we are using Jiri's age as x we know Jiri is 12 years old.
