Algebra.Com's Answer #316947 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! Add both equations (this is easy because the y's will cancel).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "3x = 12 --> x = 4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Replace x into either equation (I will use the first) to solve for y:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4 - y = 10 \n" ); document.write( "y = -6\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the solution (x,y) is (4, -6). \n" ); document.write( " |
