a = -2

#### Explanation:

Move 15a to the right hand side.
You get $8 = - 4 a$ and thus
$a = - 2$

$a = - 2$

#### Explanation:

$\implies 8 + 15 a = 11 a$

Add $- 15 a$ on both the sides

$\implies 8 + 15 a - 15 a = 11 a - 15 a$

$\implies 8 + 0 = - 4 a$

$\implies 4 a = - 8$

Divide both sides by $4$

$\implies \frac{\cancel{4} a}{\cancel{4}} = - \frac{8}{4}$

$\implies a = - 2$
