${\huge{\boxed{\mathbb{ANSWER\:WITH\:EXPLANATION}}}$

Hello there, first we can place our equation, which you have stated

$2d+9=19$ , this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.

First we can subtract $9$ with both sides of the equation giving us the result of $2d=10$ , this can also be represented as $2\cdot d=10$ , now just divide both sides of the equation by $2$ , our answer is $d=5$ .
