First column with a "missing": \(\displaystyle x\) is \(\displaystyle 1\) so substitute \(\displaystyle 1\) for \(\displaystyle x\) in the equation to get:

\(\displaystyle 6-2y=6\)

Now solve this for \(\displaystyle y\) and that is what should go in place of the "missing".

The others are similar.
