literal equation

Answer 1

Answer:

The answer is

$\frac{2s}{n} - l = a$

Step-by-step explanation:

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

multiply both sides by 2 to get

$2s = n(a + l)$

divide both sides by n to get

$\frac{2s}{n} = a + l$

subtract L from both sides to get the answer

$\frac{2s}{n} - l = a$
