Solving Equations Simultaneously With The TI-Nspire CAS

I finally figured out how to do this with the TI-Nspire CAS. I could not find any help on exactly how to do this so I just figured it out myself. I'm not sure if anyone else has had the same difficulties as me so I figured I would make a tutorial just in case. I hope this helps! Feel free to leave any comments and/or suggestions.

Thank you SO MUCH! This helped a TON! Can you tell me how to solve an equation on ti-nspire with just one variable? Wanting to be able to double check exponent and log anwers while taking an exam. 49^x = 7^(x+2)?

@jandmchild Glad it helped! For the equation that you have, all you need to do is input the equation into your calculator as you have typed here using the same method in this video. The only difference is that you will only need to use one row in the matrix and just specify "x" as the variable.

Nice Video.Can you tell me it is okay to input complex number(like (a+bi) or polar form) and solve?

[AGKyle2010]

@ccya965042 Yea you can do that. Just be sure to use the imaginary "i" letter for that portion of the complex number.
