Algebra.Com's Answer #283682 by checkley79(3341)![]() ![]() ![]() You can put this solution on YOUR website! X & Y should have one solution each.\r \n" ); document.write( "\n" ); document.write( "However in this case - there are no solutions for x or y because these two eauations are the same. \n" ); document.write( "6x - 3y = 9 \n" ); document.write( "2x - y = 3 MULTIPLY THIS EQUATION BY -3 & ADD. \n" ); document.write( "6x-3y=9 \n" ); document.write( "-6x+3y=-9 \n" ); document.write( "----------- \n" ); document.write( "0x+0y=0 \n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
