Suppose a, b, c and d are constants such that a is not zero and the system below is consistent for all possible values of f and g. What can you say about the numbers a, b, c and d? Justify your answer.
ax1+bx2=f
cx1+dx2=g
I've been trying to think about it but I can't seem to get any closer to a solution. My basic thoughts is that we must perform some row reduction, but I'm not really sure how we should do it. I would love some help.
