Algebra.Com's Answer #26783 by stanbon(75887)![]() ![]() ![]() 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. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
