$a = 135$

#### Explanation:

$\frac{a - 15}{6} = 20 \text{ } \leftarrow$ multiply both sides by 6

$a - 15 = 6 \times 20 \text{ }$ add 15 to both sides

$a = 120 + 15$

$a = 135$

To check, substitute the solution into the original equation.

$L H S = \frac{135 - 15}{6} \text{ } \mathmr{and} R H S = 20$

$= \frac{120}{6}$

$= 20$

LHS = RHS, therefore the solution is correct.
