Question:
The solution of the differential equation dy/dx = e^(x-y) is:
A. e^y = e^x + C
B. e^x = e^y + C
C. y = e^x + C
D. x = e^y + C
Step-by-Step Solution
Key Concept: Separate the variables.
Step 1: dy/dx = e^x / e^y => e^y dy = e^x dx. Step 2: Integrate: ∫ e^y dy = ∫ e^x dx => e^y = e^x + C.
Correct Answer: A
