How to use a solve block to solve a system of equations.

To create a solve block:

1. provide initial guesses for x, and y--they don't have to be too accurate but they must be present.  
2. Type the keyword  Given (don't press the spacebar, or the keyword will become a comment).
3. Type in the equations using the equivalence equals sign ( "ctrl =" key sequence).  
4. End the solve block with a call to the Find  function with the variables x and y (Find(x,y) =  ).

See the Solving Equations for details.
