1. Consider the following system of simultaneous linear equations in five variables: a + 3b 2c + d- 6e = 12 a + 4b + 4c2d+5e = −1 2a +9b+2cd-3e = 15 3a + 13b + 6c - 5d - 2e = 12 (a) Express this system in the form Av = w, where A is the coefficient matrix of the system. Write down the augmented matrix A' of this system, and convert it to reduced row echelon form via a sequence of elementary row operations. (b) Calculate the rank of A and A', and use your answers to say whether the system has no solutions, a single unique solution, or multiple solutions. (c) Write down the solution set of the system of equations
