Not Understanding This Problem Physics Is Getting A Lot Harder An Atwood Machine

Not understanding this problem. Physics is getting a lot harder. 🙁

An Atwood Machine is constructed using two wheels (with the masses concentrated at the rims). The left wheel has a mass of 1.9kg and radius 24.36 cm. The right wheel has a mass of 2.8 kg and radius 27.39 cm. The hanging mass on the left is 1.83 kg and on the right 1.19 kg.

What is the acceleration of the system? The acceleration of gravity is 9.8m/s^2.

Answer in units of m/s^2.

The model is here:
