Pamela is 12 years younger than Jiri. The sum of their ages is 38. What is Jiri's age?​

Answer:Jiri's age is 25. Step-by-step explanation: Let P = Pamela's age and J = Jiri's age. Then                                            (1)        P = J - 12                                            (2) P + J = 38 Substitute (1) into (2)         J - 12 + J = 38 Add 12 to each side                J + J = 50 Combine like terms                    2J = 50 Divide each side by 2                  J = 25 Jiri's age is 25.
