How to use ode45 to plot time evolution of a system?

I'm stuck on this question for coursework.

"Use ode45 to make a plot of the time evolution of the system with parameters α1, α2 = 10 and β, γ = 2. Assume initial conditions u0 = 2, v0 = 1. "

The differential equations are:

I have no idea where to start. I'm not really sure how to use ode45 and the explanations online are a bit too complicated for me. If somebody could help me understand how to use ode45 then I might be able to take it from there!

Hi Jan

My problem is that I don't know where to start and so can't show anything I've tried yet! I have added this to the question.
