WebSep 11, 2024 · By the method of integrating factor we obtain. exy2 = C1 2 e2x + C2 or y2 = C1 2 e2 + C2e − x. The general solution to the system is, therefore, y1 = C1ee, and y2 = C1 2 ex + C2e − x. We now solve for C1 and C2 given the initial conditions. We substitute x = 0 and find that C1 = 1 and C2 = 3 2. WebClue: System of Two Equations. Created by. Alaura Bailey.
