Age of Junior Schmidt is $= 12$

#### Explanation:

Age of Grandpa Schmidt$= 75$

Let Age of Junior Schmidt be $= x$

Then 7 times $x$ and less 9 is grandpa's age, it is -
$= 7 x - 9$

Then we form an equation -

$7 x - 9 = 75$

Solve it for $x$

$7 x = 75 + 9 = 84$

$x = \frac{84}{7} = 12$

Age of Junior Schmidt is $= 12$
