2. Solution initial condition;

We have transformed the original system into a diagonal system.

The solution to this diagonal system of linear differential equations
(as in example 1) is

The general solution to the system of linear differential equations is
\(y_1 = 4c_1e^{6x} - c_2e^x\)
\(y_2 = c_1e^{6x} + c_2e^x\)
