SOLUTION: I need help solving this equation. I have the answer but I need help on how to work it out. The equation is s=n/2(a+t). The answer is a=2s-nt/n

Question 56984: I need help solving this equation. I have the answer but I need help on how to work it out. The equation is s=n/2(a+t). The answer is a=2s-nt/n
Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
The equation is s = n/2(a+t).
:
Here's how I understand the problem:
s = . Solve for a
Multiply equation by 2, this gets rid of the denominator:
2s = n(a + t)
:
Divide equation by n:
= a + t
Subtract t from both sides:
= a

Not sure how you got the answer that you gave.
