I think of a number
I think of N
multiply it by 3
I get 3N
and then add 21
I get 3N+21
my answer is 74
I write 3N+21 = 74\r\n" );
document.write( "\r\n" );
document.write( "So I have the equation\r\n" );
document.write( "\r\n" );
document.write( "     3N+21 = 74\r\n" );
document.write( "\r\n" );
document.write( "I add -21 to both sides to cancel the +21 on the left\r\n" );
document.write( "\r\n" );
document.write( "  3N+21-21 = 74-21\r\n" );
document.write( "\r\n" );
document.write( "        3N = 53\r\n" );
document.write( "\r\n" );
document.write( "Then I divide both sides by 3 to cancel the 3\r\n" );
document.write( "\r\n" );
document.write( "       \"%283N%29%2F3=53%2F3\"\r\n" );
document.write( "\r\n" );
document.write( "         N = \"53%2F3\" or  \"17%262%2F3\" \r\n" );
document.write( "\r\n" );
