Find all Values of K so Augmented Matrix is a Consistent System | Linear Algebra Exercises

Find all values of k for which the given augmented matrix corresponds to a consistent linear system. We solve three problems of this sort in today's linear algebra lesson. We do some row operations to reduce our matrices then consider the restrictions imposed on k based on the corresponding system of linear equations. #linearalgebra

[@SuperVazz]

thanks,it helped a lot.

[@user-ic1ru4gp8q]

Im so happy, thanks😊

[@WrathofMath]

You're welcome 😊

[@hussamoulan2260]

Thanks bro

[@WrathofMath]

Welcome!

[@adrianashah2367]

where is the continuation

[@TheNitroPython]

I am personally a little confused on how you row reduced the matrix.

[@qasimali-fl7vs]

I tkhink in 19b question x1+kx2=1 , not -1(correct me if i am wrong)

[@s9raw]

Why 1? It’s written in the question-1

[@user-ni5th5oz2c]

20b's answer is all values of k?

[@EpicEmpire24]

Yes

[@mianhabiburrehman8586]

(4+k)x=0
for all values of k.
correct me if i am wrong

[@pipertripp]

That's what I got. It's similar to 19b.

[@gdotone1]

why didn't you solve for k?

[@birt1023]

You lost me at 19b
