Consider the matrices(adsbygoogle = window.adsbygoogle || []).push({});

A=

(1 5 -3)

(2 x -3)

B=

(1 3 -1)

(3 x -1)

Find x so A and B have the same line space.

I tried to do this problem but I was stuck with

A=

(1 (x-5) 0)

(0 (x-10) 3)

B=

(1 3 -1)

(0 (x-9) 2)

Also, I'm not really sure of what they mean by same line space.
