So first you add 8 and 2 to get 10. This means that Kevin is 10 years old now. If he is currently twice as old as his brother it means that you divide 10 by 2 to get 5. Kevin's brother is 5 years old.
Answer: 5 years old
Answer: 5 years old
k = 2b
k - 2 = 8
k - 2 = 8
Add 2 to both sides:
k = 10
Plug in 10 for 'k' in the first equation:
10 = 2b
Divide 2 to both sides:
b = 5
So his brother is 5 years old now.
k - 2 = 8
k - 2 = 8
Add 2 to both sides:
k = 10
Plug in 10 for 'k' in the first equation:
10 = 2b
Divide 2 to both sides:
b = 5
So his brother is 5 years old now.
