You can put this solution on YOUR website!
x + 5y = 4
\n" ); document.write( "2x – 5y = 2
\n" ); document.write( "-------------- Add them
\n" ); document.write( "3x + 0y = 6
\n" ); document.write( "3x = 6
\n" ); document.write( "x = 2
\n" ); document.write( "Substitute for x in either eqn
\n" ); document.write( "2 + 5y = 4
\n" ); document.write( "5y = 2
\n" ); document.write( "y = 2/5
\n" ); document.write( "
\n" ); document.write( "
\n" );
