.Write the system in the form Ax = B and use x = A-'B to solve the system for each matrix В. x1 + 2x2 + 5x3 = b1 %3D 2x1 + 3x2 + 8x3 = b2 -x1+ x2 + 2z = b3 -2' (a) B 5 (b) B = ( 2 (c) B = | 5

I would like this part in written form without fractions. Also, Leading ones and pivot columns if possible. I am struggling to approach this problem.

X, + 2х2 + х3 + 4x4 2x, + 4x2 + X3 + 5x4 4x1 + 8x2 + 3x3 + 13x4 -1 0. = Consider the system = -2 (a) the system. Write down a vector equation that is equivalent to the above system. You do not need to solve (b) the system. Write down a matrix equation that is equivalent to the above system. You do not need to solve (c) operations to bring A to a row echelon form. Let A be the coefficient matrix corresponding to the above system. Use elementary row

Is this how you do number 5? Is my solution correct?
