Initial Value Problem for a System of Linear Differential Equations

In summary, we discussed an initial value problem with a set of coupled equations. By substituting $X=BY$, we decoupled the equations and were able to solve them separately. After solving for $Y$, we substituted it back into the original equation to get the solution for $X$. However, there was an error in the calculation of the diagonal matrix $D$ which resulted in incorrect values for $Y$. After correcting the error, we were able to obtain the correct solution for $X$ as a function of $t$.

How can we find the inverse of $A$?? I got stuck right now...

I'm not quite clear on the problem.
Aren't all $m_i$ values given? (Wondering)
Wouldn't it only be $m_1$ that we make variable?
