Use gauss-jordan elimination to solve the following linear system.
x – 6y – 3z = 4
–2x – 3z = –8
–2x + 2y – 3z = –14

Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store. which equation can be used to determine the approximate shoe size, s, for a foot length of x inches? s = x – 2 s = 2x – 10 s = x + 6 s = 2x + 4

Aye asap pls ! markin da brainiest too ! btw da step choices are all add, distribute, divide, n subtract
