Perform the indicated operation and simplify:
\n" ); document.write( "6x + 9/3x - 15 * x - 5/4x + 6\r
\n" ); document.write( "\n" ); document.write( "Is the middle of this expression really 15 * x? If so, it is can be rewritten 15x. If that is really a plus or minus, then it is the number 15 and x are two different terms. Check this.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First: group the terms of this expression so that those with an x and those that are just numbers are together.\r
\n" ); document.write( "\n" ); document.write( "6x + 9/3x - 15x -5/4x + 6 or 6x + 9/3x + x - 5/4x + 6 - 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "9/3 can be simplified to 3. 6-15 can be simplifed to -9\r
\n" ); document.write( "\n" ); document.write( "6x + 3x - 15x -5/4x + 6 or 6x + 3x + x - 5/4x - 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then, combine the like terms. \r
\n" ); document.write( "\n" ); document.write( "(6 + 3 - 15 - 5/4)x + 6 or (6 + 3 + 1 - 5/4)x + - 9\r
\n" ); document.write( "\n" ); document.write( "-29/4 x + 6 or 35/4 x - 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
