Question

so my question is 

 

Determine the value of h such that the matrix is the augmented matrix of a linear system with infinitely many solutions.

 

/6    -5   /    8     /

/18    h  /    24   /

 

 

h=?

Answer 1

The bottom x is three times the top x

The bottom constant is three times the top constant

The bottom y is ..................

 

So h is ..........
