(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Equation 1: m1g - T1 = m1a (for first mass)

Equation 2: T2 - m2g = m2a (for second mass)

Equation 3: (T1-T2)R = IA (for pulley; A = rotational acceleration)

What are the steps I must take to get the final equation that describes the motion of the system:

(m1-m2) g = (m1+m2+I/R^2)a ??

Thank you

2. Relevant equations

3. The attempt at a solution

I can figure out a = g(m1-m2)/(m1+m2) BUT i dont know how to factor in equation 3?
