The questions are read solve the differential equation
For a all i could do was separate the right side to e^y +e^sinx while for b) I simplified to e^(x-2y). I am trying to read the text which is not much help since the sample questions are a lot more easier. Please help
If you're in some sort of calculus class, it might be a good idea to review your algebra with a site like Purplemath. You should probably know all of the "elementary algebra" topics and most of the "intermediate algebra" topics. You'll find exponentiation rules like the one Chris L T521 mentioned there.
