Algebra.Com's Answer #116750 by mizjoice(22) ![]() You can put this solution on YOUR website! Take it piece by piece:\r \n" ); document.write( "\n" ); document.write( "5 times a number, rewrite as 5x\r \n" ); document.write( "\n" ); document.write( "plus -2, nothing to rewrite there, that's already simplified,\r \n" ); document.write( "\n" ); document.write( "added to nine times a number, rewrite as 9x.\r \n" ); document.write( "\n" ); document.write( "Now, rewrite as an equation:\r \n" ); document.write( "\n" ); document.write( "5x-2+9x = (See, it already looks better!)\r \n" ); document.write( "\n" ); document.write( "Now combine like terms:\r \n" ); document.write( "\n" ); document.write( "5x + 9x -2= 14x - 2 \n" ); document.write( " |
