Answer:
1. (a + 18) = 5(a - 2)
2. Hussein is 7 years old.
Step-by-step explanation:
1. Let the current age of Hussein is a years.
Now question states that after 18 years, Hussein will be five times as old as 2 years ago.
Age after 18 years = (a + 18) years
Age of Hussein 2 years ago = (a - 2) years
By the statement given above equation will be
(a + 18) = 5(a - 2)
2. To calculate the age we will solve the equation.
a + 18 = 5(a - 2)
a + 18 = 5a - 10
18 = 5a - a - 10
18 = 4a - 10
4a = 18 + 10
4a = 28
a = [tex]\frac{28}{4}=7[/tex] years
Therefore, Hussein is 7 years old.
