Algebra.Com's Answer #1573 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! Looking at the 3 equations, the coeeficients of z match the RighHand side values, so the solution, x=y=0 and z=1 satisfies your equations...without doing any calculations.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "To \"prove\" this solution, you can do substitution/elimination etc or use Cramer's Rule...determinants of certain matrices. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Using Cramer's rule, gives x=y=0 and z=1.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "jon \n" ); document.write( " \n" ); document.write( " |
