the sum of two numbers is 18. their difference is 22. what are the numbers?
\n" ); document.write( ":
\n" ); document.write( "x + y = 18
\n" ); document.write( "x - y = 22
\n" ); document.write( "-------------addition eliminates y, find x
\n" ); document.write( "2x = 40
\n" ); document.write( "x = 20
\n" ); document.write( ":
\n" ); document.write( "Find y:
\n" ); document.write( "20 + y = 18
\n" ); document.write( "y = 18 - 20
\n" ); document.write( "y = -2
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution in 2nd equation:
\n" ); document.write( "20 -(-2) = 22 \n" ); document.write( "
\n" );
