Equation for position: x'= y(x - vt)

y is the gamma constant.

Then in the first step to find the velocity, a derivative was done:

dx'= y(dx - vdt)

From the above equation, it was used to find the relativistic equation for velocity, and I understand that part. but what I don't understand is what the differential operator was is in the derivative, such as something like d/dt. If I take d/dt to both sides of the equation, then I do not see how the above equation was found. Could someone please explain to me what the differential operator was used to find the above equation? Thanks.
