x, Ali's age
\n" ); document.write( "y, Father's age\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28y-7%261%2F2=5%28x-7%261%2F2%29%2Cy%2B7%261%2F2=2%28x%2B7%261%2F2%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28y-7%261%2F2=5x-37%261%2F2%2Cy%2B7%261%2F2=2x%2B15%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28y-7%261%2F2%29-%28y%2B7%261%2F2%29=%285x-37%261%2F2%29-%282x%2B15%29\"---------obviously using elimination method; you finish this.
