Answer:

B

Step-by-step explanation:

A. 37 isn't a number sentence

B. 49 + (-12) = 49-12. They're the same thing  because 49 minus 12 can also be written as 49 plus negative 12

C. 49 + 12 doesn't equal 49-12

D. 12- 49 = -37 which isn't equivalent to 49-12.

Hope this helps!!!
The choice that represents an equivalent number sentence of the equation would be B
