Homework Statement
Show that if the linear equations x1 + kx2 = c and x1 + lx2 = d have the same solution set, then the equations are identical ( k = l, c = d)
The Attempt at a Solution
since the two equations have the same solution set, they are equal for every value of c and d so x1 + kx2 = x1 + lx2 and I can reduce this down to k = l, what about c and d though? The problem statement tells me, I believe, c = d should I even show this?
