Algebra.Com's Answer #171755 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! 3/14x - 1/14y = 1/2 \n" ); document.write( "Multiply both sides by the LCD which is 14:\r \n" ); document.write( "\n" ); document.write( "14(3/14x - 1/14y) = 14*1/2 \n" ); document.write( "3x - y = 7 \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For the second equation, you need to put it in standard form. Remove parentheses first:\r \n" ); document.write( "\n" ); document.write( " 6x = 2y+10\r \n" ); document.write( "\n" ); document.write( " 6x - 2y=10\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide both sides by 2: \n" ); document.write( "3x-y=5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The system to be solved is \n" ); document.write( "3x-y=7 \n" ); document.write( "3x-y=5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, subtract the second equation from the first equation: \n" ); document.write( "3x-y-(3x-y)=7-5 \n" ); document.write( "3x-y-3x+y=2 \n" ); document.write( "0=2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "NO WAY!! Since there is NO SOLUTION, this means that the lines are PARALLEL, and the system is said to be \"INCONSISTENT.\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Dr. Robert J.
