Use Gauss-Jordan row reduction to solve the given system of equations. HINT [See Examples 1-6.] (If there is no solution, enter NO SOLUTION. If the system is dependent, express your answer in terms of x where the x-coordinate is 'x' and both the y-coordinate and z-coordinate are functions of x.) x + X - y 0.75x 0.5y + x + y + (x, y, z)= Z = -1 7z = 9 0.25z = 15 Z = 3 X Use Gauss-Jordan row reduction to solve the given system of equations.
