$x = \frac{1}{A} \left(2 d + e + y\right)$

#### Explanation:

We have: $A x - y = 2 d + e$

Let's add $y$ to both sides of the equation:

$R i g h t a r r o w A x - y + y = 2 d + e + y$

$R i g h t a r r o w A x = 2 d + e + y$

Then, let's divide both sides by $A$:

$R i g h t a r r o w \frac{A x}{A} = \frac{1}{A} \left(2 d + e + y\right)$

$\therefore x = \frac{1}{A} \left(2 d + e + y\right)$
