Let T be the cost of a tennis ball, G the cost of a golf ball.
\n" ); document.write( "\"4T%2B3G=1025\"
\n" ); document.write( "\"2T%2B5G=1125\"
\n" ); document.write( "Multiply eq. 2 by (-2) and add to eq. 1,
\n" ); document.write( "\"4T%2B3G-4T-10G=1025-2250\"
\n" ); document.write( "\"-7G=-1225\"
\n" ); document.write( "\"highlight%28G=175%29\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Then use either equation to solve for T.
\n" ); document.write( "\"4T%2B3%28175%29=1025\"
\n" ); document.write( "\"4T=1025-525\"
\n" ); document.write( "\"4T=500\"
\n" ); document.write( "\"highlight%28T=125%29\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Tennis balls are $1.25 and golf balls are $1.75 each.
\n" ); document.write( "
\n" ); document.write( "
