AI Thread Summary
To solve for I in the equation mgh=(2y^2/t^2)(m+I/r^2), the user is advised to rearrange the equation carefully, ensuring to apply operations to both sides equally. The discussion emphasizes that multiplying only one side is incorrect and suggests continuing with the rearrangement process. Additionally, there is a recommendation to learn LaTex for clearer equation presentation in future posts. The user is encouraged to keep working through the steps as they are close to finding the solution. Understanding proper algebraic manipulation is crucial for solving the equation effectively.

Well ... just keep going
 
so do i mutiply r^2 to the other side? then - the m?

You can't multiply only one side of the equation

But you're close. BTW You have two possibilities
