Hello, can someone help me solve this. All parts belong to one question. Thank you

In a model for forest growth, the portion of the forest occupied by gaps and adult trees at time t are described by a(t), g(t), respectively. The dynamics of this system are described by the following compartment model: dg da = -0.2g + 0.1a, = 0.2g - 0.1a dt dt (a) Find the general solution to the system.(b) Find the portion of the forest that is occupied by adult trees at time t.(c) When t - co, what is the portion of the forest that will be occupied by adult trees
