Then, enter the SOLVE environment and select Solve equation…, by using:

‚Ï@@OK@@. The corresponding screen will be shown as:

The equation we stored in variable EQ is already loaded in the Eq field in the

SOLVE EQUATION input form. Also, a field labeled x is provided. To solve

the equation all you need to do is highlight the field in front of X: by using

˜, and press @SOLVE@. The solution shown is X: 4.5006E-2:

This, however, is not the only possible solution for this equation. To obtain a

negative solution, for example, enter a negative number in the X: field before

solving the equation. Try 3\@@@OK@@˜@SOLVE@. The solution is now X: -

3.045.
