Let A be a fixed 2x3 matrix. Prove that the set(adsbygoogle = window.adsbygoogle || []).push({});

[itex]W={x \in R^{3} :Ax=[^{1}_{2}]} [/itex] (2x1 matrix 1 on top 2 at the bottom)

what does the information after the ":" mean? is it a condition?

I dont understand this problem. Can anyone help me out?
