Let x be Pamela's age, and y Jiri's age. "Pamela's age is 2 times Jiri's age" can be represented by x = 2y "The sum of their ages is 63" So x + y = 63 We can now create a system of 2 equations: x = 2y (1) x + y = 63 (2) Let's take the algebraic value of x from equation (1) and replace it in equation (2): x + y = 2y + y = 3y So 3y = 63 Divide both sides by 3 to isolate y on a side and its value on the other: (3y)/3 = 63/3 y = 21 So Jiri's age is 21 years old. Hope this Helps! :)
