You can put this solution on YOUR website!
1st equation:
\n" ); document.write( "2x - y = 2
\n" ); document.write( "2x = 2 + y
\n" ); document.write( "divide it by 2:
\n" ); document.write( "x = 1 + y/2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2nd equation:
\n" ); document.write( "\"y%5E2-4x=4\"
\n" ); document.write( "\"y%5E2-4%281%2By%2F2%29=4\"
\n" ); document.write( "\"y%5E2-4-2y=4\"
\n" ); document.write( "\"y%5E2-4-2y-4=0\"
\n" ); document.write( "\"y%5E2-2y-8=0\"
\n" ); document.write( "factorize it:
\n" ); document.write( "(y - 4)(y + 2) = 0
\n" ); document.write( "y - 4 = 0 --> y = 4 --> x = 1 + 4/2 = 1 + 2 = 3
\n" ); document.write( "y + 2 = 0 --> y = -2 --> x = 1 + (-2)/2 = 1 - 1 = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the solutions are: (3, 4) and (0, -2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
