How should i solve a system of linear equations in complex numbers using TI 89 titanium calculator?

the equations are:


(0.2655%26lt;-10.59)X + (-0.2)Y = 20%26lt;45


(-0.2)X + (0.3041%26lt;9.462)Y = 0


The angles are in degrees.How should i solve a system of linear equations in complex numbers using TI 89 titanium calculator?
try using sqrt(-1) for i??





My calculator is the casio equivalent though, and that doesnt work on mine





I dont think its possible on mine.





Perhaps read the manual?

TI 89 titanium calculator refuse to do linear equations.. not sure why.. but they dont work correctly, i showed mine to my teacher when we were doing linear equations, she told me that i needed to get a new calculator because that one didnt accept what you need to do
