answer only question3 b thank you ,i will vote you positive

3. In this questions the symbols (Si), (S2), (S3), (S4) are understood as the labels for various systems of linear equations. You are not required to justify your answer in this part. Suppose the solution set of (Si) is {(1+s, 2 3,3 2s) |s is a real number}. (a) Write down one possible system (S2) which contains exactly two linear equations, and to which (Si) is equivalent. (Hint. Write x1 = 1+ S, X2 = 2 S, X3 1+s, x2 = 2 S, X3 = 3 2s, and obtain two equations by 'eliminating's. Make sure that when you solve the resultant system, you indeed obtain the correct solution set.) (b) Write down one possible system (S3) which contains exactly three pairwise distinct linear equations, none being a multiple of another, and to which (S1) is equivalent. (c) Write down one possible system (S4) which contains exactly four pairwise distinct linear equations, none being a multiple of another, and to which (S1) is equivalent
