$x < 3$

Explanation:

What I would do is subtract 26 to both sides of the expression to cancel out the 26 on the left side and to get 13x by itself like this:

$13 x + 26 < 65$
$- 26 - 26$

When you do that you should get

$13 x < 39$

Now divide both sides by 13 to get x by itself like this:

$\frac{13 x}{13} < \frac{39}{13}$

When you do that division you're left with x on the left hand side and 3 on the right hand side, with a less than sign separating them like this:

$x < 3$
