Use the matrix capabilities of a graphing utility to write the augmented matrix corresponding to the system of linear equations in reduced row-echelon form. Then solve the system. (If there is no solution, enter NO SOLUTION. If the system is dependent, express x, y, and z in terms of the parameter a.) 3x + 3y + 12z = 15 4z = 5 x + y + 2x + 5y + 20z = 19 8z = -x + 2y + 4 (х, у, 2) - 15,5,19,4

Write the system first as a vector equation and then as a matrix equation. 8x₁ + x2 3x3 = 9 4x2 + 3x3 = 0 Write the system as a vector equation where the first equation of the system corresponds to the first row. Select the correct choice below and fill in any answer boxes to complete your choice.

Given A and b to the right, write the augmented matrix for the linear system that corresponds to the matrix equation Ax = b. Then solve the system and write the solution as a vector. Write the augmented matrix for the linear system that corresponds to the matrix equation Ax = b. 1 4 -3 0 A = 2 b = 3 2 5 - 12
