Question 151220: By performing row of operations on augumented matrix, I am having a hard time trying to determine if these equations are independent, dependent, or inconsistent.
x+y+z=11
x-y+3z=5
2x+2y+2z=15
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
multiplying the 1st row by 2 gives 2x+2y+2z=22
comparing this with the 3rd row shows inconsistence
