I WILL GIVE BRAINLIEST AND ALL MY POINTS I HAVE IF SOMEONE CAN JUST GIVE ME THE CORRECT ANSWERS TO THE QUESTIONS BELOW. I really need to get all these questions right and these are the only two I can’t figure out. Please help.
What is the solution of the system of equations?

{-3x - 4y - 3z = -7

{2x - 6y + 2z = 3

{5x - 2y + 5z = 9

A. (5,-2,7)

B. (-5,2,7)

C.(5,2,-7)

D. No solution

Use a matrix to find the solution to the system of equations.
