Answer:

<em>Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift</em>

Step-by-step explanation:

<u>Equations</u>

Let's make:

x = the number of years from now

Karim now is 22 and Ziad is 8. x years from now Karim will be

22 + x years old and Ziad will be

8 + x years old.

Karim will give Ziad a wonderful gift when:

22 + x = 3(8 + x)

22 + x = 24 + 3x

Solving:

x = -1

This means that Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift
