You can put this solution on YOUR website!
The equation is s = n/2(a+t).

\n" ); document.write( "Here's how I understand the problem:
\n" ); document.write( " s = $\"%28n%2F2%29%28a%2Bt%29\"$ . Solve for a
\n" ); document.write( "Multiply equation by 2, this gets rid of the denominator:
\n" ); document.write( "2s = n(a + t)
\n" ); document.write( ":
\n" ); document.write( "Divide equation by n:
\n" ); document.write( " $\"2s%2Fn\"$ = a + t
\n" ); document.write( "Subtract t from both sides:
\n" ); document.write( " $\"%282s%2Fn%29-+t\"$ = a
\n" ); document.write( ":
\n" ); document.write( "Not sure how you got the answer that you gave. \n" ); document.write( "
