You can put this solution on YOUR website!

\n" ); document.write( "assuming you have a system to solve:\r
\n" ); document.write( "\n" ); document.write( " $\"25x%5E2-y%5E2=36\"$ ....eq.1
\n" ); document.write( " $\"5x%2By=2\"$ .....eq.2
\n" ); document.write( "-------------------------------\r
\n" ); document.write( "\n" ); document.write( " $\"5x%2By=2\"$ .....eq.2.......solve for $\"y\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"y=2-5x\"$ ....eq.2a.substitute in eq.1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"25x%5E2-%282-5x%29%5E2=36\"$ ....eq.1...solve for $\"x\"$ \r
