The answer is no, because the first two equations are right but the third equation equals -16 instead of -15. So the answer is no (2,-2,4) is not the solution to all the system of equations.

If you consider every letter in the word "tennessee" to be unique there is 9!, or 362880 different ways to arrange the letters. So let's use that as a starting point.
Now there's 4 e's, which we really don't care how they're arranged. So divide by 4!, or 24. Giving us 362880/24 = 15120 different ways to arrange the letters.
There's also 2 n's. So divide by 2!, giving us 15120/2 = 7560 different ways.
Don't forget the s's either. So another division by 2!, giving 7560/2 = 3780 different ways.
And there's no more duplicate letters, so the final figure is 3780 different ways to arrange the letters in the word "tennessee".</span>
Convert yards to feet
1yard=3ft
times both sides by 7
7 yards=21ft
7yards 2ft, 6in is
21ft+2ft and 6in or
23ft and 6in
so from 23ft 6in to 30ft 9 in is how much?
30ft, 9in-23ft, 6in=
30ft-23ft, 9in-6in=
7ft, 3in
he was 7ft, 3in short
