Answer:

Jessica is currently 3 years old and her father is 27 years old.

Explanation:

System of Equations

Let's call:

x = Jessica's age

y = Jessica's father's age.

There are two conditions:

1: Jessica's father is 24 years older than her or, equivalently:

y = x + 24

2: Three years from now, he will have five times her age.

Three years from now, Jessica will have x+3 years, and her father will have y+3 years, thus:

y + 3 = 5( x + 3 )

Substituting the first condition into the second:

x + 24 + 3 = 5( x + 3 )

Operating:

x + 27 = 5x + 15

Subtracting x and 15:

27 - 15 = 5x - x

12 = 4x

Solving:

x = 12 / 4 = 3

x = 3

y = 3 + 24 = 27

y = 27

Jessica is currently 3 years old and her father is 27 years old.
