What is wrong with this equation?

I am able to get a solution from this:

[x,y] = dsolve('Dx=-3*x+(5/2)*y','Dy=(-5/2)*x+2*y','t')

But I get an error from this:

[x,y] = dsolve('Dx=2*x+(-5/2)*y','Dy=(9/5)*x-*y','t')

Is there a particular reason why dsolve will not solve this?

hi,

no its fine, remove the asterisk

 [x,y] = dsolve('Dx=2*x+(-5/2)*y','Dy=(9/5)*x-y','t')
