Nia solved the equation -1.98 = 5.2v + 13.1. her answer was v = -2.9. she is fairly confident about her answer, but wants to do a quick check of her solution using estimation to make sure her answer is reasonable.

which of the following shows a good check of her answer?

-2 = 5(-3) + 13
-3 = 5(-2) + 13
-1 = 5(-2) + 13
-2 = 5(-2) + 13
