I’m struggling with Balancing Redox Reactions, can someone help me solve this so I can hopefully understand it?

Cr2O7^2-(aq)+ I^-(aq)-> Cr³⁺(aq)+ I2(s)

Receive

1. Get the redox pairs,  which are the one in this example
2. In acidic condition the reduction get H+  and water will be obtained, if oxygen is in the molecule
3. The oxidation is vise versa
4. Balance the charges by adding electrons
5. Get the equations equal by the electrons by multiplikation
5. Do addition of both equation
6.Short H+, water and electrons
