The unit rate is 13 over 2 (13/2) or 6.5 over 1 (6.5/1)
When you estimate, make your numbers easy. I would round 2.12 to 2 and 58 to 60. then you would have 2 * 60 = 120 which would be close to 122.96
Thanks for your question!

First add the 8 to both sides, canceling out the 8 in the right and adding it to the 19 on the left, making it 27. Multiplying undoes division so, After that, multiply by three on both sides, canceling out the three on the right and multiply 27 by 3, making it 81.
