document.write( "Question 867076: hi everybody, i have a question from functions that i can't quite solve the question is use any value to make f(x)=0 and the formula is f(x) = 3x+2/2x+4 and the answer is x= -2/3 so do anybody here have an ideal on how to solve this question? any help will be greatly appreciated.

\"f%28x%29+=+%283x%2B2%29%2F%282x%2B4%29\" Start with the given function\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0+=+%283x%2B2%29%2F%282x%2B4%29\" Replace f(x) with 0 (since \"f%28x%29+=+0\")\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0%282x%2B4%29+=+3x%2B2\" Multiply both sides by 2x+4.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0+=+3x%2B2\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x%2B2+=+0\" Flip the equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x+=+0-2\" Subtract 2 from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x+=+-2\" Subtract\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x+=+-2%2F3\" Divide both sides by 3.
\n" ); document.write( "
\n" );
