Write the given system as a matrix equation and solve by using the inverse coefficient matrix. Use a graphing utility to perform the necessary

Write the given system as a matrix equation and solve by using the inverse coefficient matrix. Use a graphing utility to perform the necessary calculations. 8x1 + 3x2 - 4x3 -7x19x29x3 4x1 - - 3x4 = 40.8 - x4 = -30.5 8x3 + 7x4 = 2.2 6x12x29x3 + 2x4 = 40.5 Find the inverse of the coefficient matrix. (Round to four decimal places as needed.) Solve for x and X2. 95 16 882-8-3 6 = X2= (Simplify your answers. Type integers or fractions.)
