In Exercises 30-36, display the augmented matrix for the given system. Use elementary operations on equations to obtain an equivalent system of equations in which x 1 appears in the first equation with coefficient one and has been eliminated from the remaining equations. Simultaneously, perform the corresponding elementary row operations on the augmented matrix. 30. 2 x 1 + 3 x 2 = 6 4 x 1 - x 2 = 7
