Answer:

ıllıllı ıllıllı

Step-by-step explanation:

22. 55.45

23. 1.4

24. Let Salma's age be n years.  

After 15 years, Salma will be (n + 15) years  

Therefore:  

n + 15 = 4n  

Subtract n from each side of the equation.  

n + 15 - n = 4n - n  

Combine like terms:  

n - n = 0  

4n - n = 3n  

Therefore:  

15 = 3n or  

3n = 15  

Divide each side by 3  

3n/3 = 15/3  

n = 5  

Therefore:  

Salma is 5 years old now.  

In 15 years Salma will be (5 + 15) = 20 years.
