Consider the system: x+2y+3z=6 2x + 5y +3z=7 x + 8z = 14 a. Write the system as a matrix equation in the form of Ax = b b. Find A-¹ using elementary row operations and the inverse algorithm (show steps completely and carefully. No technology). c. Solve the system Ax = b using your result from part (b) and matrix multiplication. Show the basic steps (though you do not need to show the detail of the matrix multiplication process -- that can be done "in your head"). Your solution should be written as x = (a column matrix, as required for the multiplication)
