Question

A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. What is the number of wolves in the state on January 1?

Which equation can be used to find the number of wolves in the state on January 1?


w + 23 = 84

w−23=84

w−84=−23

23−w=84

Answer 1

w - 23 = 84

Explanation:

W is the amount of wolves they had in the state for the first year. If 84 wolves is 23 less than what they had originally you would be subtracting that amount to get 84.

Hope this helps

Answer 2

w+23=84 is the answer for that problem because in order to find the answer u need to do the opposite of subtraction
