.

(This displays the value assignment screen.) 

Assign 0 to Y: 

0E

Assign 1 to A: 

1E

Input an initial value for X (Here, input 1): 

 

1E

Assign –2 to B: 

-2E

Specify the variable you want to solve for: 

f

(Here we want to solve for X, so move the highlighting to X.) 

Solve the equation:

.

• Press  

E to return to the value assignment screen. Then you can assign different values 

to the variables, change the initial value, and solve again.

• An error message (Can’t Solve) will appear if SOLVE is unable to solve the equation.

• If natural display is selected for the calculator’s display format, the value assignment 

screen shows only one variable at a time. 

• Use  

c and f to move the highlighting between variables and select the one you want 

to input.

A Scrolling the Equation on the Value Assignment Screen

If an equation is too long to fi t on the variable assignment screen, you can scroll it left and 
right to bring other parts of it into view. To enable scrolling, press  

z6(LOOK).

Use the

e and d keys to scroll the equation right and left.

To return the equation to its initial view after scrolling, press  

J.

A SOLVE Precautions

• Depending on the initial value you input for the equation, SOLVE may not be able to 

produce a solution. If this happens, input a different initial value that you estimate is close 
to the actual value of the variable you are solving for, and try again.

• SOLVE may not be able to produce a solution for an equation, even though one actually 

exists.
