I need help getting to the rref of the matrix. I struggle with what manipulations to do to get a rref
1. Solve the linear systems using augmented ma solutions or whether there are infinitely mar many give the solution parametrically. a) x1 3x3 3x3 8 2x1 + 2x2 + 9x3-7 x2 + 5x3 =-2 -9X1 + 12x2-6x,-0 . 6x1 +8x2-4x3 = 0 2. Compute theproduct
