Deleting One Equation or Its Variables (DELET)
To delete an equation or its variables:
1. Display the equation.
2. Press  in the SOLVE menu.
3. To delete the equation, respond  to both questions:
  
  
(If the entry has no variables allocated, then only the second question
appears.)
4. To delete just the variables, respond  to
  
. This preserves the equation.
Deleting All Equations or All Variables in the Solver
(
@c
)
To delete all the equations in the Solver, or just all the variables in all the
equations:
1. Display the SOLVE menu. It doesn’t matter which equation is
displayed.
2. Press
@c
. To delete all equations, respond  to both
questions:
  
  
3. To delete just the variables, respond  to
  
. This preserves all equations.
Writing Equations
An equation in a book looks different from an equation in the Solver. A
numerator and denominator might be separated by a bar, such as
