You can put this solution on YOUR website!
Assuming your equation looks like this:\r
\n" ); document.write( "\n" ); document.write( "\"s=x%2Asqrt%282%2Ag%29%2F%28x%2By%29\"\r
\n" ); document.write( "\n" ); document.write( "you can multiply both sides by (x+y)\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2By%29%2As=%28x%2By%29%2A%28x%2Asqrt%282%2Ag%29%29%2F%28x%2By%29\"\r
\n" ); document.write( "\n" ); document.write( "the x+y factor on the right hand side will cancel out leaving you with
\n" ); document.write( "\"%28x%2By%29%2As=x%2Asqrt%282%2Ag%29\"\r
\n" ); document.write( "\n" ); document.write( "Then, distribute the s among the (x+y) factor on the left hand side\r
\n" ); document.write( "\n" ); document.write( "\"sx%2Bsy=x%2Asqrt%282%2Ag%29\"\r
\n" ); document.write( "\n" ); document.write( "move the sx term to the right by subtracting it from both sides\r
\n" ); document.write( "\n" ); document.write( "\"sx-sx%2Bsy=x%2Asqrt%282%2Ag%29-sx\"\r
\n" ); document.write( "\n" ); document.write( "which wil leave you with\r
\n" ); document.write( "\n" ); document.write( "\"sy=x%2Asqrt%282%2Ag%29-sx\"\r
\n" ); document.write( "\n" ); document.write( "then finally divide both sides by s to isolate y\r
\n" ); document.write( "\n" ); document.write( "\"y=%28x%2Asqrt%282%2Ag%29-sx%29%2Fs\"\r
\n" ); document.write( "\n" ); document.write( "which could also be expressed as\r
\n" ); document.write( "\n" ); document.write( "\"y=%28x%2Asqrt%282%2Ag%29%29%2Fs-x\"
\n" ); document.write( "
\n" );
