Harriett's age is 3 more than 2 times angela's age. if the sum of their ages is 51, how old is each girl?

Angela's age  = 16 years

Harriett's age  = 35 years

Step-by-step explanation:

Let Angela's age be x

Harriett's age = 2x + 3

x + 2x +3 = 51

        3x  = 51 -3

        3x = 48

          x =48/3

          x  = 16

Angela's age  = 16 years

Harriett's age  = 35 years
