Answer:
<em>Jessica is currently 3 years old and her father is 27 years old.</em>
Step-by-step explanation:
<u>System of Equations</u>
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.
