De’Shaun is 5 years younger than Nemo. Adela is twice as old as Nemo. Jefferson is 3 times as old as De’Shaun. Altogether their ages total 50. Find each person’s age

  Age of Nemo = 10  years

De'shaun's age =  5 years

  Adela's age    = 20 years

Jefferson's age =  15 years

Step-by-step explanation:

Age of Nemo = x years

So, De'shaun's age = x - 5

Adela's age    = 2*x = 2x

Jefferson's age  = 3* (x -5) = 3*x - 3*5 = 3x -15

Total age  = 50

x + x - 5 + 2x + 3x - 15  = 50   {Combine like terms}

x + x + 2x + 3x - 5 - 15 = 50

                    7x   - 20   = 50

                               7x = 50 + 20

                               7x = 70

                                 x =  70/7 = 10

                Age of Nemo = 10 years

De'shaun's age = 10 - 5  = 5 years

                Adela's age    = 2* 10 = 20 years

            Jefferson's age  =  3*10 -15 = 30 - 15  = 15 years
