题目内容：
mathematica 解微分方程组
In[39]:= DSolve[{x'[t] == r*x[t],x[0] == x0},x[t],t]
During evaluation of In[39]:= DSolve::deqn:Equation or list of equations expected instead of True in the first argument {(x^\[Prime])[t]==r x[t],True}.>>
Out[39]= DSolve[{Derivative[1][x][t] == r x[t],True},x[t],t]
怎么解不出来?
