1. The problem statement, all variables and given/known data

y'(xk1-k2)+y(xk3-K4)=K5

Where k1-k5 are constant.

2. Relevant equations

3. The attempt at a solution

I have no idea what to do...

Does xk1 mean k1 times x?

What course is this for? I can think of a number of ways to do this (it is what is called a "linear first order differential equation with variable coefficients") but which would be appropriate for you depends upon what techniques you know.

Hi,

xk1 means k1 times x.

I guess i need the easiest techniques.

Write it in the form,
$$y'+p(x)y=q(x)$$
And use the integrating factor method.
