Solve the following linear system.

I don't understand how to get the free variables as well as the first column. I got it to RREF but after that I'm confused. I keep getting it wrong. Please help! Here is the link to the question. https://ibb.co/FBvLgRc

Here are a couple hints: x2 is a free variable, but you do not want all zeros for that variable. Similarly for the other free variables x5 and x6. For example try +s [4 1 0 0 0 0]. Also, for that last vector I got [7 0 -2 2 0 1], but you might want to check.

Here is a Desmos graph you can use to confirm. Use the sliders on x2,x5,x6 to see the values for the original equations are always the same. desmos.com/calculator/m3jtzsbpdw
