This is the ONLY one i got left so if anyone can help i'd really appreciate it...

------------

Using the system of linear equations below, answer the following questions.

2x1 + 5x2 + 7x3= -2

-6x1 - 15x2 -21x3= 6

a) (5 marks) Find the solution of the given system of linear equations, Q, that is closest to the point P(0, -7, 0).

b) (5 marks) What is the distance between the point P(0, -7, 0) and the point Q, from above?

------------------

ok here are the answers, these are 100% sure right but i dunno how the program go them...

The correct answers to parts a) and b) are:

Q(0.846, -4.885, 2.962)

distance = 3.737
