Question

Help with Augmented Matrix problem

Answer 1

if it's a consistent linear system, the rows must be multiples of each other, i.e, the system must hold true.

notice that the coefficients of the second row are (-4) times the first row. so h is 7/-4 = -7/4

Answer 2

wait, when we mean consistent linear system, we mean there are infinite number of solutions...?

Answer 3

yes.

since the two lines are on top of eachother

Answer 4

Ah okay I was thinking of using Gaussean elimination, thanks a lot!
