For the given system, 2x1 - xy + 3ry = d 3x1 + 12 - 513 = b (1) -5x1 - 5x2 + 21x3 =a+b+c (a) Solve the system (1). (b) If x3 = 0 in system (1), than solve ist two transformed equation. (c) If x1 = 0 in system (1), than solve ist and 3rd transformed equation. (d) What do you know geometrically about the solution obtained in part (a), (b), (c) and explain with the help of graph for each case in your own word. Question Number: 02 (05, 05, 05, 04, 05) Identify the numbers between a and c, arrange all types of number in your own proper and unique interesting way. and attempt the following: (a) Find HCF and LCM of of all even numbers from your list with pair of two numbers and so on .
