Answer:

The answer is

[tex] \frac{2s}{n} - l = a[/tex]

Step-by-step explanation:

[tex]s = \frac{n}{2} (a + l)[/tex]

multiply both sides by 2 to get

[tex]2s = n(a + l)[/tex]

divide both sides by n to get

[tex] \frac{2s}{n} = a + l[/tex]

subtract L from both sides to get the answer

[tex] \frac{2s}{n} - l = a[/tex]
