Solving Equations with More Than One Answer
The calculator only returns one solution even if more than one
possible solution exists. When this is the case, you can first
enter a guess by assigning a value to that variable and then
asking the calculator to solve your equation. The TI-73 always
chooses the solution closest to that guess. However, the guess
must be within the bound limits; otherwise, you get an error.
Your variable
values may vary.
