    Your equation : D=E*Y
    E is an n×n matrix and you can assume that it had an inverse matrix as stated in your problem.
    Let's assume E^-1 is the inverse matrix.
    Now multiply that matrix from the write side to the equation and you get:
    E^-1*D = E^-1*E*Y
    Note that the matrix matrix multiplication is not commutative ! so order matters you have to multiply the matrix from both sides to the left otherwise you don't have an equality anymore.

    Now a Matrix multiplied by it's inverse Matrix
    (in your example E^-1*E ) always becomes the identity matrix let's call that matrix Id
    So you get: E^-1*D = Id*Y

    Note that any Matrix multiplied by the identity matrix is by definition the matrix itself.
    Therefore: Y = E^-1*D
    Where E^-1 is the inverse matrix of E

      Oh I forgot to mention that of cause the matrices D and Y need to have the right dimension in order to do an matrix matrix multiplication but in your problem it is stated that both Y and D have the dimension n x 1 which is fine.

    The answer to your matrix question depends on which pill you choose.
    Lol. The math you are doing is something that leaked out of my brain long ago. I will say, that when I went to high school, that was beyond us. I had to wait till college for that. I give you a lot of credit for being involved with such math in high school!

    I'm really sorry I can't help you with that. 😕 I suck at math and I've never had to do that kind of exercises.

    I'm pretty sure Y = n in your example, because:

    E = n × n (or n²). So if D = E × Y, that should be the same as D = n × n × Y, because Y is the same as 1 × n.

    Don't hold me to this. It'sbeen a long time since I've done mathematics like this. 👍

      I believe so. I'm not completely sure. I use trigonometry at work all the time for figuring out bends in pipe runs, but like I said, I haven't done mathematics like your question in ages.

      I love how someone downvoted me, meanwhile no one as of yet has even tried to supply you with any answer, let alone a correct answer. LOL
