Let Kim = k, and her sister = s
k = 2s
k + s = 60
First, plug in 2s for k in the equation "k + s = 60"
2s + s = 60
Simplify
(2s + s) = 60
3s = 60
Isolate the s. Note the equal sign. What you do to one side, you do to the other. Divide 3 from both sides
3s/3 = 60/3
s = 60/3
s = 20
Her sister is 20 years of age.
