Ti 89, Solving multiple equations with complex numbers

Click For Summary
SUMMARY

The discussion centers on solving multiple equations with complex numbers using the cSolve method on the TI-89 calculator. The user encountered an error stating "too many arguments" when attempting to solve the equations 80a + 240b = 0 and (80+J79.975)a-80b = 50. It was concluded that the correct format for complex numbers is a + b*i, not a + b*J. Additionally, the user discovered that the variables 'a' and 'b' cannot be used as algebraic variables in the TI-89, but other variables work without issue.

Homework Statement


So, I know how to solve multiple equations using the cSolve method on the ti 89, but for some reason when I try to solve the following...

80a + 240b = 0 and (80+J79.975)a-80b = 50 by using the following syntax...


cSolve(80a + 240b = 0 and (80+J79.975)a-80b = 50 ,{a,b})

I get a message saying that there are too many arguments, what am I doing wrong?

Can anyone helpme with this? I am not having any luck at all, is this even possible?
 
When all else fails, try reading the instructions.

The proper complex number has a format of a + b*i, not a + b*J
 
I know that haha, as it turns out, in my calculator for some reason you cannot use a and b as algebraic variables, it works perfectly fine using any other variable XD
