You can put this solution on YOUR website!
1) - x + y = 2
\n" ); document.write( "2) x + y = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " 0 + 2y = 6 → I added equation 1) to equation 2): -x+x=0, y+y=2y, 2+4=6
\n" ); document.write( " 2y = 6 | :2 on both sides
\n" ); document.write( " y = 3 → Now you subsitute y with 3 in equation 2):\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + y = 4
\n" ); document.write( "x + 3 = 4 | -3 on both sides
\n" ); document.write( "x = 1 → To varify this solution you do the same in equation 1):\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-x + y = 2
\n" ); document.write( "-x + 3 = 2 | -3 on both sides
\n" ); document.write( "-x = -1 | : -1
\n" ); document.write( "x = 1 → The solution is varified.\r
