for which the matrix M has an inverse. (b) Find, in terms of p, the coordinates of the point where the following planes intersect 2x - y + z = p Зх — бу + 4z — 1 Зх + 2у — z =0 (c) (i) Find the value of q for which the set of simultaneous equations 2x - y + z = 1 3x – 5y + 4z = q Зх + 2у — z= 0 can be solved. (ii) For this value of q, interpret the solution of the set of simultaneous equations geometrically.
