On Tuesday kali by five CDs on Wednesday Half of all the CDs that she had were destroyed on Thursday there were 22 left how many did she have on Monday

39

Work:

(x+5) / 2=22

We will reverse this equation.

We will start by moving the 2 through inverse operations.

22x2=44

Now we have the equation

x+5=44

We will subtract 5

44-5=39

x=39

the unknown variable equals 39

Kali had 39 CDs on Monday
