1. If the following system has infinitely many solutions, -7x - 4y - 6z = 6 -4x

Question

1.

If the following system has infinitely many solutions,

-7x - 4y - 6z = 6

-4x + 5y - 6z = 9

-23x + 16y + hz = k

then h = ? and k = ? (find h and k)

For the following questions, it is easier if you look here:

since writing all of them will be very tedious.

Thank you very much. For this one, if you wish, it is OK if you just leave the solutions without explanation. But please make sure they are correct.
