Find solutions such that A: no solution, B: Unique solution C: Infinitely many

Find solutions such that A: no solution, B: Unique solution C: Infinitely many

Question Details:

X1 + hX2 = 2

4X1+8X2= k

I get that h = -15 will be inconsistent (no solution)

h = Real number expect -15 will be unique ( i think)

I don't know how i will get infinitely many.

only unique answers for this

I wanted to ask this question original :( sorry. Thank you.

1 -3 -2

5 h -7

If, -5R1 + R2

= 1 -3 -2

0 15+h 3

now when h = -15 => inconsistent, when h doesn't equal -15 unique solutions. Infinite is not possible?
