Determine the value(s) of h such that the matrix is the augmented matrix of a consistent linear system?1 h 2 5 20 8 Ok so I got 2h cannot = - 20 Then divide by 2 and got h cannot equal = -10? Is this correct?

Is this correct? No it is not correct. You need the matrix to be non-singular, determinate not zero.
I have to make it into a 1 0 0 1 Is that what you mean?

Ooh haha I got -4, does it look correct now?

Its 4 since (20-5h)x2=-2 So it's a augmented matrix of a consistant linear system if h cannot = 4?
Hello, Oldspice1212! Determine the value(s) of h such that the matrix is the augmented matrix of a consistent linear system. . . The system is consistent if its determinant is not equal to zero. If , we have: . . . Hence: .
^ yup I got it, thanks guys
