2. Simultaneous equations (a) In a system of forces, the relationship between two forces F, and F2 is given by the simultaneous equations: 3(F, + F2) – 0.75 = 0

F,2 + F2 – 1 = 0 Find F, and F2. ) At a socially distanced concert 100 tickets are sold; the cheaper ones cost£3.50 and the more expensive ones cost £5.50. The total receipts for ticket sales were £500. Find the number of each type of ticket sold. c) Explain why the following system of linear equations cannot be solved: 2а + 4b 3 7 4a² + 16b2 + 16ab = 49
