Question

4. Aaron is 5 years younger than Ron. Four years later, Ron will be twice as old as Aaron. Find their present ages. answer this question briefly

Answer 1

Answer:

1

Step-by-step explanation:

Let Ron’s present age be x.  

Then Aaron’s present age = x - 5

After 4 years Ron’s age = x + 4, Aaron’s age x - 5 + 4.  

According to the question;  

Ron will be twice as old as Aaron.  

Therefore, x + 4 = 2(x - 5 + 4)  

⇒ x + 4 = 2(x - 1)  

⇒ x + 4 = 2x - 2

⇒ x + 4 = 2x - 2

⇒ x - 2x = -2 - 4

⇒ -x = -6

⇒ x = 6

Therefore, Aaron’s present age = x - 5 = 6 - 5 = 1

Answer 2

Step-by-step explanation:

Let Ron's age = x

Aaron 's age= (x - 5)

4 years later,

Ron age= 4+x

Aaron 's age= 2(x- 5)

x + 4= 2x- 10

x+ 4= 2x-10

x- 2x= -10-4

-x=-14

x= 14

Ron age= 14

Aaron age= 9
