I'm trying to solve the following simultaneous equations:




What I've been done, is put it in matrix form, ie:

k \begin{vmatrix} 0.01 & 0.01 & -0.01 \\0.01 & 0.04 & 0.01 \\-0.01 & 0.01 & 0.09 \end{vmatrix} = \begin{vmatrix} 0.005 \\0.01 \\0.02 \end{vmatrix}


However, I realise that it's incorrect as I've missed out the last equation.

Can someone please advise me how I go about solving it simulatenously, in order to find the x's and the constant k?

Thanks

Solve the system you have in your matrix form, which should give you each of the x_i in terms of k.

Then simply use the last equation and you should be able to work out k.
