Answer:

Pedro age = 54 ; Jorge age = 18

Step-by-step explanation:

Pedro age = P

Jorge age = J

3J = P

J + P = 72

we have to substitute the value of P in the second equation

J + 3J = 72

we have solve the equation

4J = 72

J = 18

we have to subistute this value in the first equation

3*18 = P

P = 54
