alright so first of all, you have to make 10x the subject of the formula, to do that, you need to subtract 400 from both sides,
so now you get 10x=6429 -400
which is 10x=6029
but what I dont understand is that the answer would be none of the options, are you sure that you wrote the question correctly?
Yeah , i wrote it right. You see I'm taking a pretest on this computer class, so it gives me the questions even if they don't make sense. It's troublesome but normally it's the closest to the actual answer.
hmm well the answer would 6029/10 which is pretty far off from all of those answers :/
