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?

请先登录，再回答此问题。

hi,
no its fine, remove the asterisk
[x,y] = dsolve('Dx=2*x+(-5/2)*y','Dy=(9/5)*x-y','t')
