Step 1.1

Add $\frac{5}{7}$ to both sides of the equation.

$\frac{a}{7} = \frac{6}{7} + \frac{5}{7}$

Step 1.2

Combine the numerators over the common denominator.

$\frac{a}{7} = \frac{6 + 5}{7}$

Step 1.3

Add $6$ and $5$ .

$\frac{a}{7} = \frac{11}{7}$

Step 2

Since the expression on each side of the equation has the same denominator, the numerators must be equal.

$a = 11$
