You can put this solution on YOUR website!
Ok first identify variables
\n" ); document.write( "x=Tony
\n" ); document.write( "y= Tony's brother
\n" ); document.write( "----------------------------------------------------------------------------------------------------------------
\n" ); document.write( "Plug these into the equations
\n" ); document.write( "x+y=29
\n" ); document.write( "y-x=5
\n" ); document.write( "-------------------------------------------------------------------------------------------------------------------
\n" ); document.write( "Eliminate to get one variable
\n" ); document.write( "x+y=29
\n" ); document.write( "-x+y=5
\n" ); document.write( "So you would get 2y=34---> y=17
\n" ); document.write( "-------------------------------------------------------------------------------------------------------------------
\n" ); document.write( "If Tony's brother is 17, then Tony is 5 years younger --->17-5= 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Tony is 12 years old
\n" ); document.write( "
\n" );
