You can put this solution on YOUR website!
Let x be your friend's age.\r
\n" ); document.write( "\n" ); document.write( "Given : \"%28x-13%29+=+%28x%2B5%29%2F2\"
\n" ); document.write( "\"2%28x-13%29+=+x%2B5\"
\n" ); document.write( "\"2x+-+26+=+x+%2B+5+\"
\n" ); document.write( "\"x+=+31\"\r
\n" ); document.write( "\n" ); document.write( "Check your answer. Is 31 - 13 equal to (31+5)/2 ???
\n" ); document.write( "
