(3) Problem 1 Please provide a typewritten solution! I will be very grateful!

Problem 1. Consider the following system of equations
X1 + 7x3 + x4 + 3x5
= 5
xi + 2x2 + x3 – 3x4 + 5x5
3
2.x1 + 3x2 + 5x3 + 5x4 + 9x5
= 7
Write down a matrix A and a vector b for which this system of linear
equations can be expressed in matrix form as Ax
row echelon form of the augmented matrix (A | b). Hence find the general
solution of the system of linear equations Ax = b (erpressing your solution
in vector form).
