Algebra.Com's Answer #8346 by rapaljer(4671) You can put this solution on YOUR website! In your first step you lost an x. It should be \n" ); document.write( "-5x - 1 = 6x + 54\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The next step is to get all the x terms on one side. You do this by getting rid or \"undo\"ing the x terms on one side. Since you have a +6x on the right side, you can undo the +6x by subtracting 6x from each side: \n" ); document.write( "-5x - 6x - 1 = 6x -6x + 54\r \n" ); document.write( "\n" ); document.write( "-11x -1 = 54\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, you have all the x-terms on the left side, you should get all the number terms to the opposite side. You need to undo the -1, by adding +1 to each side.\r \n" ); document.write( "\n" ); document.write( "-11x -1+1 = 54 +1 \n" ); document.write( "-11x = 55\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Finally, you need to undo the multiplication by the -11.
