2x -3y = 12;
x + 3y = 6;
__________(+)
3x = 18;
x = 18÷3;
x = 6;
Then, 3y = 6 - 6;
3y = 0;
y = 0÷3;
y = 0;

Answer:
what the problem?
Step-by-step explanation:
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
