You can put this solution on YOUR website!
Here is such an example:\r
\n" ); document.write( "\n" ); document.write( "0.2345x + 6.25y=3.45
\n" ); document.write( "-0.2345x -4.72y = 7.63\r
\n" ); document.write( "\n" ); document.write( "This is easier to work by elimination because
\n" ); document.write( "the coefficients in the x-terms differ only
\n" ); document.write( "in their signs. So adding the equations eliminates
\n" ); document.write( "the x terms.
\n" ); document.write( "Substiutution would require much more work.
