The average of three numbers is the sum of the numbers divided by 3. Let the numbers be X, Y and Z, then

\n" ); document.write( "\"%28X+%2B+Y+%2B+Z%29%2F3+=+V\".

\n" ); document.write( "multiply both sides by 3 to get \"X+%2B+Y+%2B+Z+=+3V\".

\n" ); document.write( "subtract Y and Z from both sides to get \"X+=+3V+-+Y+-+Z\"

\n" ); document.write( "The remaining number X is 3V- Y - Z
\n" ); document.write( "
\n" );
