Ti 89, Solving multiple equations with complex numbers

[Abide]

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 arguements, 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

I would like to offer some suggestions on how to solve this problem on the Ti 89 calculator. First, make sure that you are using the correct syntax for the cSolve method. The correct syntax should be cSolve({80a + 240b = 0 , (80+J79.975)a-80b = 50} ,{a,b}). Notice that the equations are enclosed in curly braces and separated by a comma. Also, make sure that you are using the correct variables for the unknowns (a and b). Another possible issue could be the use of J instead of the letter i for complex numbers. Try replacing J with i in the equations and see if that solves the problem. If the issue persists, it could be due to a software or hardware malfunction. In that case, I would suggest seeking technical support from the manufacturer or consulting a user manual for troubleshooting.
