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.
