 limits apply to the unknown variable value for which

you are solving. Default bounds are {M1©99,1©99}. Use these

limits to narrow the unknown value solution to a specific

range of numbers, especially if more than one answer exists.
Hint: For answers with many solutions (for example, trig

functions), consider graphing the function first to get an idea

of the most ideal (or specific) 

 limits.

 

Specify the unknown variable from the 

line. This

prompts the calculator to solve for it.
To select a variable on the 

 line, highlight the unknown

variable with the cursor, and then press b. After you press

b, a solid black square appears next to the solved

(previously unknown) variable displayed in the Equation

Variables section.
Hint: The Solver allows for a small tolerance when solving a

result, which is noticeable especially when solving complex

equations or those with multiple solutions. For example, a

result of 3.99999999999999 (instead of 4) for the equation 

is considered a correct answer.

 

For 2(L+M)=N, solve for L when N=268, and M=40, M14, and

307.

1. Define the equation on the

screen.
