document.write( "3x + 5y = 7   (1)\r\n" );
document.write( "2x + 4y = 6   (2)\r\n" );
document.write( "\r\n" );
document.write( "Multiply equation (1) by 2. Multiply the equation (2) by -3 and then add. \r\n" );
document.write( "You will get (after canceling like terms) a single equation for y:\r\n" );

document.write( "10y - 12y = 14 - 18,   or\r\n" );
document.write( "\r\n" );
document.write( "-2y = -4.\r\n" );
document.write( "\r\n" );
document.write( "Hence, y = 2. Now from (1) you can find x =  =  =  =  = -1.\r\n" );
document.write( "\r\n" );
document.write( "Answer. x = -1, y = 2.\r\n" );
