You can put this solution on YOUR website!
you have r(x) = x - 1/3 * x + 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if i read this equation correctly, then it can be simplified to:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r(x) = 2/3 * x + 5, because x - 1/3 * x = 2/3 * x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so your equation becomes r(x) = 2/3 * x + 5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you want to find r(c-3)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you replace x with (c-3) to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r(c-3) = 2/3 * (c-3) + 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify this to get r(c-3) = 2/3 * c - 2/3 * 3 + 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify further to get r(c-3) = 2/3 * c - 2 + 5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this results in r(c-3) = 2/3 * c + 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
