document.write( "Solve the system by substitution:\r\n" );
document.write( "3X + 5Y = 2\r\n" );
document.write( " Y = -X + 2 \r\n" );
document.write( "\r\n" );
document.write( "The second one is already solved for Y, so we replace\r\n" );
document.write( "the \"Y\" in \"3X + 5Y = 2\" by what Y equals to, namely (-X + 2)\r\n" );
document.write( "placed in parentheses.\r\n" );
document.write( "\r\n" );
document.write( "So instead of \r\n" );
document.write( "\r\n" );
document.write( "3X + 5Y = 2\r\n" );
document.write( "\r\n" );
document.write( "We write\r\n" );
document.write( "\r\n" );
document.write( "3X + 5(-X + 2) = 2 \r\n" );
document.write( "\r\n" );
document.write( "I will let you solve that\r\n" );
document.write( "\r\n" );
document.write( "when you do you'll get X = 4\r\n" );
document.write( "\r\n" );
document.write( "Now substitute (4) for X in\r\n" );
document.write( "\r\n" );
document.write( "Y = -X + 2 \r\n" );
document.write( "\r\n" );
document.write( "Y = -(4) + 2\r\n" );
document.write( "\r\n" );
document.write( "Y = -2\r\n" );
document.write( "\r\n" );
document.write( "So the solution is (X, Y) = (4, -2)\r\n" );
