213.
• Pressing  will clear all of the coefficients to zero.
4. After all the values are the way you want, press .
• This will display a solution. Each press of  will display another
solution. Pressing  while the final solution is displayed will return to
the Coefficient Editor.
• A message appears to let you know when there is no solution or when
there are infinite solutions. Pressing  or  will return to the
Coefficient Editor.
• You can assign the currently displayed solution to a variable. While
the solution is displayed, press  and then the key that
corresponds to the name of the variable to which you want to assign
it.
• To return to the Coefficient Editor while any solution is displayed,
press .
To change the current equation type setting: Press (Simul
Equation) or (Polynomial), and then press , , or . Changing
the equation type causes the values of all Coefficient Editor coefficients to
change to zero.
