Answer:
you didn't add options for the sentences, but
x-5 =-10 (add 5 to both sides to get x alone)
x= -5
so anything that has to do with x equaling - 5 would be correct
after reading through the sentences, the correct answer is:
a number subtracted from five is equal to negative ten
because that sentence is saying " 5 - n = - 10 " and that's not what's happening
