I have been playing around with an HP 50g and I can't seem to get the mslv to work in RPN. I am using the example from the small guide that comes with the calc.

The equation is

[Sin(x)+ y,x+ Sin(y)=1]

[x,y]

[0,0]

I have tried using the small tic marks and not using them. It works fine if you switch to alg mode. Can someone tell me what I am doing wrong?

Thanks
