Question 910865: The system of linear equations has a unique solution. Find the solution using Gaussian elimination or Gauss-Jordan elimination.
x − 2y + z = −3
y + 2z = 19
x + y + 3z = 34
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
x − 2y + z = −3
-(x + y + 3z = 34)
-3y - 2z = -37
y + 2z = 19 |multiplying thru by 3 to eliminate the y variable by adding the Eqs
4z= 20
z = 5
y = 9 , y = -27/-3
Will Let You finish it Up determining x = 10
ordered triple (10, 9, 5)
