Given dat Y=6, Z=-7

\n" ); document.write( "my mum was (X+Y+Z+3)yrs wen she gave birth to me.
\n" ); document.write( "Now she's (80-X+Y)yrs.
\n" ); document.write( "
\r\n" );
document.write( "Since (X+Y+Z+3) = (X+6-7+3) = X+2,\r\n" );
document.write( "\r\n" );
document.write( "your mum was X+2 years old when she gave birth to you.\r\n" );
document.write( "\r\n" );
document.write( "Since (80-X+Y) = (80-X+6) = 86-X,\r\n" );
document.write( "\r\n" );
document.write( "she's 86-X years old now. \r\n" );
document.write( "\r\n" );
document.write( "Your present age is how much older she is now than then:\r\n" );
document.write( "\r\n" );
document.write( "So your present age = (86-X)-(X+2) = 86-X-X-2 = 84-2X\r\n" );
document.write( "

\n" ); document.write( "& my age is given.
\n" ); document.write( "
\r\n" );
document.write( "No it isn't, you only said it is given, but you didn't give\r\n" );
document.write( "it, so it isn't given.  If it were given, we could set 84-2X\r\n" );
document.write( "equal to it, and then we could find X and then substitute\r\n" );
document.write( "the value we got for X in 86-X to find out how old your mother \r\n" );
document.write( "was when you were born.\r\n" );
