I have just gotten my new Ti-nspire CAS calculator and seem to be stumped. I have created my two equations from my mesh analysis of a circuit.
Loop I2: I1(2+j2)+I2(8-j2)=12
Loop I1: I1(-j2)+I2(j-4)=0
I know I can solve this by hand but would like to learn to use my nspire. Any direction would be greatly appreciated, I feel I have tried everything I can think of and can't seem to get the result.
{{2+2i, -2i}, {8-2i, 12+i}} * {{I1, I2} = {{12, 0}} - I think this is right?
------------------------------------
Some things I've tried:
- Using dotP:
- Using cSolve:
I reviewed numerous youtube videos and instructions but couldn't seem to find a solution the resulted in the right answer. I am trying to find I2 and did the hand calculations to get I2=1.76-1.06j
Thanks in advance to any input!

Some things I've tried:
- Using dotP:
Creating the matrix of coefficients {{2+2i, -2i}, {8-2i, 12+i}}, taking the inverse (^-1) and dot-ting (dotP{}) it with [12,0] - I get 'Error Invalid data type'
- Using cSolve:
Input: cSolve(x(2+i2)+y(8-2i)=12 and x(-i2)+y(i-4)=0,x,y
Output: x=c6 and y=c7 and (then repeats equations)
