You can put this solution on YOUR website!
4x/x+1 = ?/(x+1)(x-1)
\n" ); document.write( ":
\n" ); document.write( "Replace ? with y
\n" ); document.write( "\"4x%2F%28x%2B1%29+=+y%2F%28%28x%2B1%29%28x-1%29%29\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "y(x+1) = 4x(x+1)(x-1)
\n" ); document.write( ":
\n" ); document.write( "Divide by (x+1)
