Algebra.Com's Answer #11487 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Your first step is correct: \n" ); document.write( "-2x+5y-6=-11 \n" ); document.write( "6+-2x+5y-6=-11+6 \n" ); document.write( "-2x + 5y = -5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "However, the next step is incorrect. You need to \"UNDO\" the -2x by adding +2x to both sides of the equation. It should look like this: \n" ); document.write( "2x -2x +5y = 2x - 5 \n" ); document.write( "5y = 2x -5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Next, you must \"UNDO\" the 5 that was multiplied by the y. In order to \"UNDO\" multiplication, you must DIVIDE both sides by 5. There are two ways to write this:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "OR YOU CAN WRITE: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Both answers are correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
