Jemma is three times as old as Angie. Five years from now the sum of their ages will be 34 years. What are their present ages?
Lapatulllka [165]

Answer: Angie = 6, Jemma = 18

<u>Step-by-step explanation:</u>

Let x represent the current age of Angie

              Current Age           Age 5 years from now

Angie:            x                              x + 5

Jemma:        3x                            3x + 5

5 years from now the sum of their ages is 34

                  (x + 5) + (3x + 5) = 34

                               4x + 10 = 34

                               4x        = 24

                                 x         = 6

Angle's current age is x = 6

Jemma's current age is 3x = 3(6) = 18
