    help to solve a system of equations and constraints

    How do I solve the following system of equations (and constraints?) ?
    I have not touched matrix algebra in years and have just plain forgotten.

    N1 = n1,1*Q1 + n1,2*Q2 + ... + n1,16*Q16
    N2 = n2,1*Q1 + n2,2*Q2 + ... + n2,16*Q16
    ...
    N8 = n8,1*Q1 + n8,2*Q2 + ... + n8,16*Q16

    Q1 + Q2 + ... + Q16 = 100

    Q3 > 43

    Q3 > Q4
    Q4 > Q5
    ...
    Q15 > Q16

    The values for Q1, Q2, Q5, N1, N2, ..., N8, and all the ni,j are known.

    I want to solve for the Q.

    You have 9 equations and 16 unknown values? you can solve the nine equations for 9 of the values in terms of the other 16- 9= 7. Then order the solutions according to the conditions.

    What do you mean by "order the solutions"?
