S=n%2F2%28A%2Bt%29. we can just intechange the places of S and A +t:
A+%2B+t+=+n%2F%282S%29,
A+=+n%2F%282S%29-t.

S=n/2(A+t) for A
multiply by 2
2*S=2*n/2(A+t)
2S=n(A+t)
divide by n
2S/n=A+t
add-t
(2S/n) -t=A

S=%28n%2F2%29%28A%2Bt%29 Start with the given equation.


2S=n%28A%2Bt%29 Multiply both sides by 2.


2S=nA%2Bnt Distribute.


2S-nt=nA Subtract nt from both sides.


%282S-nt%29%2Fn=A Divide both sides by 'n' to isolate 'A'.


A=%282S-nt%29%2Fn Rearrange the equation.


So the solution is A=%282S-nt%29%2Fn
