I read this in my calculus first year textbook, and Im just curious. 1. The problem statement, all variables and given/known data For differential equation dy/dx = x + y, the general solution is y = Ce^x - x -1 (the solution of which is beyond this course). Verify this by solving dy/dx. 2. Relevant equations calculus equations 3. The attempt at a solution dy/dx = Ce^x - 1 this looks nothing like x + y however. what am I missing?
