Only do 2 and 3

For each of the following systems of linear equations, write down (1) the corresponding vector equation (x1 . V1 + X2 . V2 = b) and (2) the corresponding matrix equation Ax = b. 1. 6x1 - X2 + 5x3 = 3 X1 - 8x2 + 2x3 = -10 2x1+ 4x2 -4x3 =5 2. X1 + 6x2 + 2x3 =5 3x1 - X2 + 4x3=-1 3. x1+ 5x2=5 -2x1 + 10x2 = 8 3x1 - 2x2 = 1 Y
