Construct a 3 × 3 example of a linear system that has 9 different coefficients on the left hand side but rows 2 and 3 become zero in elimination. If the right hand sude of your system is <b1,b2,b3> (Imagine this is a column vector) then how many solutions does your system have for (i) b1 = 1, b2 = 10, b3 = 100, and (ii) b1 = b2 = b3 = 0?

2. Relevant equations

Gaussian elimination method I used here:

3. The attempt at a solution

I've tried setting up a matrix in the form C|d, but I'm not sure what to put for my coefficients. Should I be putting actual numbers in that would make the system 0? I'm just really stuck on this problem.
