In 3.5 years kim will be 12 more than one half her
current age. What is Kim's current age?
K = Kim's current age
K+3.5 = Kim's age in 3.5 years.
0.5K = half Kim's current age
0.5K+12 = 12 more that one half her current age.

K+3.5 = 0.5K+12
10K+35 = 5K+120
    5K = 85
     K = 17

Checking:

In 3.5 years Kim will be 17+3.5 or 20.5.

Is 20.5 equal to 12 more than one half her current age?

Half her current age is 8.5, so yes, 8.5+12 = 20.5.

So it checks.

Kim's current age is 17.
