Answer:

Abigail is 32 and Cynthia is 24.

Explanation:

Let a = Abigail's age

Let c = Cynthia's age

a = c + 8

a -20 = 3(c - 20)

Substitute c + 8 for a into the second equation.

c + 8 - 20 = 3(c - 20) combine like terms and distribute the 3

c - 12 = 3c -60 Subtract c from both sides

-12 = 2c - 60 Add 60 to both sides

48 = 2c Divide both sides by 2

24 = c

Cynthia is 24.

Substitute 24 for c in the first equation

a = c + 8

a = 24 + 8

a = 32

Abigail is 32.
