Im trying to understand what happened in this book

they have

[itex] |I>=\frac{|1>}{\sqrt{2}}+\frac{|2>}{\sqrt{2}} [/itex]

and then [itex] |II>=\frac{|1>}{\sqrt{2}}-\frac{|2>}{\sqrt{2}} [/itex]

and then they say they superimpose these equations to get

[itex] |1>=\frac{|I>}{\sqrt{2}}+\frac{|II>}{\sqrt{2}} [/itex]

did they just add the first equations together and then renormalize

it to find the new coefficients.
