document.write( "    1)  3*y = 6-y.\r\n" );
document.write( "\r\n" );
document.write( "    2)  y*(3*y) = y*(6-y) = 2y - (6-y) = 3y - 6.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, your equation is  3y - 6 = 6,   and the solution is 3y = 6+6 = 12  ===>  y =  = 4.\r\n" );
