(Solved): Let [X=[\begin{matrix}x+y-1&0\ 0&3\end{matrix}]] and [Y=[\begin{matrix}5&0\ 0&2x-3y- ...

Let [X=[\begin{matrix}x+y-1&0\ 0&3\end{matrix}]] and [Y=[\begin{matrix}5&0\ 0&2x-3y-7\end{matrix}]] The value(s) for x for which the matrices have inverses is/are given by {x,y ?R: with x ? 2 and y?-1} No such value of x but with (y=-1) None of the given options {x,y ? R: with x ? 1 or y ? -1} {x,y?R: with x ? 2 or y?-1}
