To solve the equation A = 1/2m(s + z) for s, follow these steps:
Multiply both sides by 2 to remove the fraction:
2A = m(s + z)
Divide both sides by m to isolate (s + z) on one side:
2A / m = s + z
Subtract z from both sides to solve for s:
s = 2A / m - z
So, the equation solved for s is s = 2A / m - z.
