The problem asks to solve the equation $29 = \frac{a}{10} - 7$ for the variable $a$.

1. Problem Description

The problem asks to solve the equation $29 = \frac{a}{10} - 7$ for the variable $a$.

2. Solution Steps

To solve for $a$, we first isolate the term with $a$ by adding 7 to both sides of the equation:

$29 + 7 = \frac{a}{10} - 7 + 7$

$36 = \frac{a}{10}$

Next, to isolate $a$, we multiply both sides of the equation by 10:

$36 \times 10 = \frac{a}{10} \times 10$

$360 = a$

Therefore, $a = 360$.

3. Final Answer

$a = 360$
