In order to solve the expression:

We operate inn such a manner that x is left alone, that is:

$9-2x=35\Rightarrow9=35+2x\Rightarrow9-35=2x$
$\Rightarrow-26=2x\Rightarrow-13=x$

We have our expression 9 - 2x = 35.

In order to solve for x, we try and leave x alone, that is, we sustract 9 from both sides of the operation:

9 - 9 - 2x = 35 -9 => -2x =26

Now that we have this, we proceed to eliminate -2 from the side of x, for that we divide both sides by -2, that is:

(-2/-2)x=(26/-2) => x = -13
