1. Start with the equation:

S = \frac{n}{2} (a + l)

2. Multiply both sides by 2 to get rid of the fraction:

2S = n (a + l)

3. Divide both sides by

to isolate $a + l$:

\frac{2S}{n} = a + l

4. Subtract

from both sides to solve for

a = \frac{2S}{n} - l

So the solution is

a = \frac{2S}{n} - l
