assuming you're solving for x, the problem can be rewritten as
$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{22}} = {\mathtt{0}}$$
in which case you should start with moving 22 over by subtracting from both sides.
$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}} = -{\mathtt{22}}$$
and then divide both sides by 2.
$${\mathtt{x}} = -{\mathtt{11}}$$
hope this helps!
