# Matrix problem

hello.

this is the problem:
determine the value of h such that the matrix is the augmented matrix of a consistent linear system.

1 -3 -2
5 h -7

i tried replacing and scaling... but it seems there are always 2 variable in this.
can you guys help me solve this problem?

Is that an augmented system:

1x-3y=-2
5x+hy=-7

???

is that not?

is the answer any number... because with everynumber, there is a different solution to x and y?... probably true?

ohkay... i think i got the answer... h cannot be 15, because than it will be

1 -3 -2
0 0 3
this show that it will be inconsistent...

$$\left[\begin{array}{ccc}1 & -3 & -2 \\ 5 & h & 7\end{array}\right]$$
$$\left[\begin{array}{ccc}1 & -3 & 2\\ 0 &h+ 15 & 3\end{array}\right]$$
