    System of equations with matrices problem

    Hi. Just started matrices. How would you go about solving such an equation? Is there anything new to add with the ordinary row operation method to solve this? Cheers.


    Find x, y and z if:


    xy −2√y + 3zy = 8
    2xy −3√y + 2zy = 7
    −xy +√y + 2zy = 4

    Just make substitution as under and proceed: xy = a; sqrt y = b and zy = c. Find a, b, and c. Thereafter find x, y and z.
