If you are trying to find what $$\displaystyle n$$ is equal to in $$\displaystyle n\,=\,29.26\,-\,2k$$

When $$\displaystyle k\,=\,8.44$$, then you substitute $$\displaystyle k$$ in your equation:

$$\displaystyle \L \;n\,=\,29.26\,-\,2(8.44)$$

Then follow the Order of Operations, first multiplication: $$\displaystyle \L \;n\,=\,29.26\,-\,16.88$$

Finally subtraction: $$\displaystyle \L \;n\,=\,12.38$$
