Question: Use back-substitution to solve the system of linear equations. 1. 2. (x y + 5z = 37 y + 2z = 6 - 2y +

Use back-substitution to solve the system of linear equations.
1.

(x – y + 5z = 37 y + 2z = 6

2.

- 2y + 2z = 20 У — г3 8 z = -1 y

(x y + 5z = 37 y + 2z = 6 - 2y + 2z = 20 3 8 z = -1 y
