Chapter 8 Solving Linear Equations DaVinci Goes Linear
A code is based on the linear equation y = x + 3. Assign a number to each
letter in the alphabet. Calculate the corresponding value of y, and use it to
replace the letter in a message. For example, if C is letter 3, the corresponding value of
y is 6. So C becomes an F.
To decode a message, reverse the process. What message does the code PHHWDWVLA indicate? Click here for a hint Click here for the solution Note: Brain teasers are often open to more than one interpretation, and multiple answers may be possible.
