Step 1: Start by recognizing that the differential equation dy/dx = 2y is separable, meaning you can rewrite it to separate the variables y and x.
Step 2: Rewrite the equation as (1/y) dy = 2 dx. This separates the variables y and x, allowing us to integrate each side independently.
Step 3: Integrate both sides. The left-hand side ∫(1/y) dy integrates to ln|y|, and the right-hand side ∫2 dx integrates to 2x + C₁, where C₁ is the constant of integration.
Step 4: Solve for y by exponentiating both sides to remove the natural logarithm. This gives |y| = e^(2x + C₁). Simplify further by writing |y| = Ce^(2x), where C = e^(C₁) is a new constant.
Step 5: Remove the absolute value by considering both positive and negative values of C, resulting in the general solution y = Ce^(2x).
