Solve for a,a.

To solve the equation:

\[
6 + \frac{a}{2} = 28
\]

Follow these steps:

1. First, subtract 6 from both sides of the equation:

\[
\frac{a}{2} = 28 - 6
\]

\[
\frac{a}{2} = 22
\]

2. Next, multiply both sides by 2 to isolate \(a\):

\[
a = 22 \times 2
\]

\[
a = 44
\]

So, the solution is:

\[
a = 44
\]
