Question

Please help and tell me the answer with details!! I feel sick today

Answer 1

5 pounds. If the dog two years ago weighed two less pounds than the dog one year ago, than that is where we are counting from, and since the dog weighs three more pounds than the dog one year ago, we have to add |-2| + |3| = 5 pounds

      

Answer 2

The following should be highlighted/circled:
Last year, weight, -2 pounds.
This year, difference, 3 pounds.
Difference, two years ago.

Difference lets you know that subtraction is involved, so this is the most important part of the word problem.
