9. (Calculator ok - don't do Gaussian on this) Solve the following system of equations using matrices. If you choose to use technology to help you solve this, write the original matrix you put into the calculator and then the RREF of the matrix. If this system has infinite solutions, parameterize the solution set for full credit. Helpful tip: Remember that on the TI calculators the "Math" key can be ued along with the command > Frac to convert a matrix answer with decimals into clean fractions. 4x - 3y + 3z = 2 5x + y - 4z = 1 9x - 2y - z = 3
